That second paragraph has got to be one of the craziest comments I've seen in a long, long time here on the flip.
Racism is not tempered, nor more likely, based on a person's political affiliation. And don't throw some white supremacist crap back at me as "proof", because their political affiliation (which is not in alignment with either of our two major political parties) follows their racism, not the other way around.
Your first paragraph was correct, so imo, you should have just stuck with that. Humans can be racist. There are many, many, racist Democrats. Party affiliation makes no difference.
