Power Line links to an amazingly clear-headed op-ed in The San Francisco Chronical by Keith Thompson:

I began my activist career championing the 1968 presidential candidacies of Robert Kennedy and Eugene McCarthy, because both promised to end America's misadventure in Vietnam. I marched for peace and farm worker justice, lobbied for women's right to choose and environmental protections, signed up with George McGovern in 1972 and got elected as the youngest delegate ever to a Democratic convention.

Eventually I joined the staff of U.S. Sen. Howard Metzenbaum, D-Ohio. In short, I became a card-carrying liberal, although I never actually got a card. (Bookkeeping has never been the left's strong suit.) All my commitments centered on belief in equal opportunity, due process, respect for the dignity of the individual and solidarity with people in trouble. To my mind, Americans who had joined the resistance to Franco's fascist dystopia captured the progressive spirit at its finest.

A turning point came at a dinner party on the day Ronald Reagan famously described the Soviet Union as the pre-eminent source of evil in the modern world. The general tenor of the evening was that Reagan's use of the word "evil" had moved the world closer to annihilation. There was a palpable sense that we might not make it to dessert.

When I casually offered that the surviving relatives of the more than 20 million people murdered on orders of Joseph Stalin might not find "evil'" too strong a word, the room took on a collective bemused smile of the sort you might expect if someone had casually mentioned taking up child molestation for sport.

My progressive companions had a point. It was rude to bring a word like "gulag" to the dinner table.

I look back on that experience as the beginning of my departure from a left already well on its way to losing its bearings. Two decades later, I watched with astonishment as leading left intellectuals launched a telethon- like body count of civilian deaths caused by American soldiers in Afghanistan. Their premise was straightforward, almost giddily so: When the number of civilian Afghani deaths surpassed the carnage of Sept. 11, the war would be unjust, irrespective of other considerations.

Stated simply: The force wielded by democracies in self-defense was declared morally equivalent to the nihilistic aggression perpetuated by Muslim fanatics.

Susan Sontag cleared her throat for the "courage" of the al Qaeda pilots. Norman Mailer pronounced the dead of Sept. 11 comparable to "automobile statistics." The events of that day were likely premeditated by the White House, Gore Vidal insinuated. Noam Chomsky insisted that al Qaeda at its most atrocious generated no terror greater than American foreign policy on a mediocre day.

All of this came back to me as I watched the left's anemic, smirking response to Iraq's election in January. Didn't many of these same people stand up in the sixties for self-rule for oppressed people and against fascism in any guise? Yes, and to their lasting credit. But many had since made clear that they had also changed their minds about the virtues of King's call for equal of opportunity.

These days the postmodern left demands that government and private institutions guarantee equality of outcomes. Any racial or gender "disparities" are to be considered evidence of culpable bias, regardless of factors such as personal motivation, training, and skill. This goal is neither liberal nor progressive; but it is what the left has chosen. In a very real sense it may be the last card held by a movement increasingly ensnared in resentful questing for group-specific rights and the subordination of citizenship to group identity. There's a word for this: pathetic.

I smile when friends tell me I've "moved right." I laugh out loud at what now passes for progressive on the main lines of the cultural left.

In the name of "diversity," the University of Arizona has forbidden discrimination based on "individual style." The University of Connecticut has banned "inappropriately directed laughter." Brown University, sensing unacceptable gray areas, warns that harassment "may be intentional or unintentional and still constitute harassment." (Yes, we're talking "subconscious harassment" here. We're watching your thoughts ...).

Wait, it gets better. When actor Bill Cosby called on black parents to explain to their kids why they are not likely to get into medical school speaking English like "Why you ain't" and "Where you is," Jesse Jackson countered that the time was not yet right to "level the playing field." Why not? Because "drunk people can't do that ... illiterate people can't do that."

When self-styled pragmatic feminist Camille Paglia mocked young coeds who believe "I should be able to get drunk at a fraternity party and go upstairs to a guy's room without anything happening," Susan Estrich spoke up for gender- focused feminists who "would argue that so long as women are powerless relative to men, viewing 'yes' as a sign of true consent is misguided."

I'll admit my politics have shifted in recent years, as have America's political landscape and cultural horizon. Who would have guessed that the U.S. senator with today's best voting record on human rights would be not Ted Kennedy or Barbara Boxer but Kansas Republican Sam Brownback?

He is also by most measures one of the most conservative senators. Brownback speaks openly about how his horror at the genocide in the Sudan is shaped by his Christian faith, as King did when he insisted on justice for "all of God's children."

My larger point is rather simple. Just as a body needs different medicines at different times for different reasons, this also holds for the body politic.

In the sixties, America correctly focused on bringing down walls that prevented equal access and due process. It was time to walk the Founders' talk -- and we did. With barriers to opportunity no longer written into law, today the body politic is crying for different remedies.

America must now focus on creating healthy, self-actualizing individuals committed to taking responsibility for their lives, developing their talents, honing their skills and intellects, fostering emotional and moral intelligence, all in all contributing to the advancement of the human condition.

At the heart of authentic liberalism lies the recognition, in the words of John Gardner, "that the ever renewing society will be a free society (whose] capacity for renewal depends on the individuals who make it up." A continuously renewing society, Gardner believed, is one that seeks to "foster innovative, versatile, and self-renewing men and women and give them room to breathe."

One aspect of my politics hasn't changed a bit. I became a liberal in the first place to break from the repressive group orthodoxies of my reactionary hometown.

This past January, my liberalism was in full throttle when I bid the cultural left goodbye to escape a new version of that oppressiveness. I departed with new clarity about the brilliance of liberal democracy and the value system it entails; the quest for freedom as an intrinsically human affair; and the dangers of demands for conformity and adherence to any point of view through silence, fear, or coercion.

True, it took a while to see what was right before my eyes. A certain misplaced loyalty kept me from grasping that a view of individuals as morally capable of and responsible for making the principle decisions that shape their lives is decisively at odds with the contemporary left's entrance-level view of people as passive and helpless victims of powerful external forces, hence political wards who require the continuous shepherding of caretaker elites.

Leftists who no longer speak of the duties of citizens, but only of the rights of clients, cannot be expected to grasp the importance (not least to our survival) of fostering in the Middle East the crucial developmental advances that gave rise to our own capacity for pluralism, self-reflection, and equality. A left averse to making common cause with competent, self- determining individuals -- people who guide their lives on the basis of received values, everyday moral understandings, traditional wisdom, and plain common sense -- is a faction that deserves the marginalization it has pursued with such tenacity for so many years.

All of which is why I have come to believe, and gladly join with others who have discovered for themselves, that the single most important thing a genuinely liberal person can do now is walk away from the house the left has built. The renewal of any tradition that deserves the name "progressive" becomes more likely with each step in a better direction.
