Full Idea
Contemporary debates within modern political systems are almost exclusively between conservative liberals, liberal liberals, and radical liberals. There is little place for the criticism of the system itself.
Gist of Idea
Liberals debate how conservative or radical to be, but don't question their basics

A Reaction
[No page number given] Kekes seems to be more authoritarian, and MacIntyre is a communitarian (which can be rather authoritarian). I'm dubious about both.
