Racism:
The modification of any behaviors or communications based on the skin color or race of others.
I’ve started to point that out to people in rather obnoxious ways. If someone tries to be a “do-gooder” in front of me and talk about race in a way that shows how Liberal and tolerant and supportive they are of civil rights, I just call them a racist and accuse them of being divisive and bigoted for judging people on the basis of skin color.
It’s the only topic on which I “jam” people. I don’t let them respond. I make it very clear that — as a good Republican — I will not, under any circumstances, tolerate their racism.
