Try prompting one of your PC friends. Ask them if they have heard of "Duck Dynasty" and can they explain it to you. If they can manage 10 sentences without saying something pejorative you can color me impressed.

I posted your question on my facebook, and the first response I got was "A member of the KKK got a tv show and white trash watch it."

Granted it was Facebook, where everyone is tying to be a comedian, but still. I don't think a face to face conversation would be that different.

n=1 On that basis I am sure I could find people with in any group who are, for instance, racist, bigoted etc quite easily. The question is not: are there some people who have this or that view or belief.

I haven't seen it, but is it political? Criticism of politics is "fair". Criticism of poverty, etc is not.

Or do you excuse your PC friends when they call these people mean words, because you agree with them?

Every 4 years My "PC" friends almost unanimouisly call republicans rednecks and nazi's and bigots, fascists, and rapists, etc etc etc. Why is it impossible for people to think that after so many years of that, those people get angry.

Even in this thread, trump supporters are called racist, because they want to restrict immigration.

Wait! Trump's pronouncements are prejudiced. Its not just "restricting immigration." Everyone on the Republican platform is for "restricting immigration." He specifically thinks that Mexican immigrants and Muslim immigrants in particular should be restricted. Granted people are guilty of lumping in religious prejudice with racism. But that isn't your main issue with it.

That is not a poor position, or a southern position. I don't think you can conflate criticism of that position with prejudice against republicans. Most republicans are against targeting members of a religion or race.
