The evident panic of the progressive mind stems from a paradox as old as progressivism in America. Progressives see themselves as the only legitimate representatives of ordinary people. Yet their vision of what democracy requires frequently conflicts with what majorities believe and how they choose to live.Leftists (my preferred term) won't ever relinquish any of their beliefs. Conservatives and libertarians will need to fight them with equal relentlessness, as long as American civilization exists to be defended.
Add to this the progressive belief that human beings can be perfected through the rule of experts, and you have a recipe—when the people make choices contrary to progressive dictates—for generating contempt among the experts for the people whose interests they claim to alone represent. And not just contempt, but even disgust at diversity of opinion, which from the progressive's perspective distracts the people from the policies demanded by impartial reason.
The progressive mind is on a collision course with itself. The clash between its democratic pretensions and its authoritarian predilections has generated within its ranks seething resentment for, and rage at, conservatives. Unless progressives cultivate the enlightened virtues they publicly profess and free themselves from the dogmatic beliefs that undergird their political ambitions, we can expect even more harrowing outbursts to come.
