College liberalism is a concept invoked by conservatives, generally modern
Market Fascists who are appalled by the fact that unlike the rest of
society at large,
college campuses often have a small percentage of the population who are concerned with
injustice,
poverty,
environmental destruction, things that used to be called 'social ills.'
To these conservatives, the fact that in the midst of a huge population of jocks, money hungry business students, detached drug users, and religious cult members, there are a small number of young people with ideals is unacceptable. This is especially galling to the Authoritarian personality in question because they have a complicated resent/envy relationship with those who have ideals.
They actually claim victimhood with the ludicrous claim that universities are repressive of conservative ideas. They often cite the fact that many of the humanities faculty have liberal ideas, completely ignoring the fact that the departments that really effect public policy, such as Economics, Political Science, and Law, generally have very conservative faculty and students.
They often like to cite the fact that college students are middle or upper middle class, as though this somehow renders their concern for the less fortunate and their concern for the overall quality of life in and direction of society any less valid.
