No, your own strawman definitions of multiculturalism and diversity suck. The pseudo-intellectual deconstructionist fad you incorrectly call "PC" swept through some segments of academia in the 70s and 80's. Aside from providing a convenient whipping boy for conservatives, deconstructionism had a negligible impact on our broader culture.

But, by all means, keep whipping that dead horse. The central theme of this campaign season will be that conservatives are out-of-touch and stuck in the 20th century. As is nicely illustrated by Ralph7's rants against Marxism.
