Yep. That rubs me the wrong way too.

One characteristic of truly earnest people is that they're non-judgemental and open to new ideas and experiences. If one can get past the boilerplate, there's some really cool ideas in postmodernism. I think PG is being the opposite of earnest in that pithy, incurious takedown.
