Varieties of criticism
Conservative criticism has nothing much to do with "left-wing" or "right-wing", because left-wing people are often very conservative, in the defined sense, while right-wing people can also be very radical, in the defined sense. The difference between "radical" and "conservative" has more to do with the belief in whether "a change to something genuinely new" is really possible and necessary. Radicals typically believe strongly that such change is highly desirable and necessary, and that it can be achieved. Their criticism is that there is "not enough" change. Conservative critics, by contrast, are very skeptical about any such change, because they feel the change is really "just another form" of something that already exists.
Traditionalist conservatism
Literary traditionalist are often linked with political conservatives and the right-wing while contrasted with experimental works and the avant-garde, which in turn are often linked with progressives and the left-wing. Postmodern writer and literary theorist John Barth, said: "I confess to missing, in apprentice seminars in the later 1970s and the 1980s, that lively Make-It-New spirit of the Buffalo Sixties. A roomful of young traditionalists can be as depressing as a roomful of young Republicans".
