Racism = Bad in any form.
Evil = subjective, varying from culture to culture.
Generally, if I find someone like that that acts with good intentions but is still hateful of people simply because of the melanin content of their skin, I will ridicule them for their ignorance as they ridicule others for their ethnicity.
I happen to be Lebanese and I did in fact receive a lot of ignorant slurs and insults from white people on 9/11. It just further fueled my annoyance with the ignorance that we allow to go on in America. It's made me hateful likewise, but not against everyone else. There are signs I look for with people that I choose to hate and it has nothing to do with their skin color, it's how big of a chauvinist backwards ignorant asshole they are.
If they're gonna stand there and call me "towel head" or "sand ******" in a serious hateful manner then fuck them, I hope they die before for their time. The world is better off without failed abortions like them and their neanderthal brain activity. They deserve every shortcoming and defeat in left they get.
Other than that, I'm an okay person to get along with. I enjoy racial humor with it's meant simply as that: humor. Good fun, lighthearted ethnic jokes from people that appreciate the meaning to it. Generally, this is other ethnic people or white people that wish they weren't so white.
