" Since ideologies of the left are commitments to an imagined future, to question them is to provoke a moral rather than an empirical response: Are you for or against the equality of human beings? To dissent from the progressive viewpoint is not a failure to assess relevant facts but an unwillingness to embrace a liberated future. It is, therefore, to will the imperfections and injustices of the present order. In the current cant of the left, it is to be “racist, sexist, classist,” a defender of the status quo. That is why not only radicals, but even those who call themselves liberals, are instinctively intolerant towards the conservative position. "
