Are you saying that the demographic you are talking about is special in using prejudice as the marker of evilness (as opposed to religious affiliation or whatever), or in taking that sort of attitude at all?
Sort of the latter. Conservatives tend to think people evil for supporting things like gay marriage and abortion - things that all sides agree are supported by one side and opposed by the other. Or to think people fundamentally good, but naive and misguided - everyone agrees poverty is bad, but conservatives think food stamps make it worse, so they oppose liberals who support food stamps.
People who reject both labels seem to regard both conservatives and liberals as cute little bumbling fools who want to do good and thus deserve a pat on the head and a lol...
