Well, I figure it's because I have this way of getting under people's skin, regardless of race.
With white people, they often get their agression out passively, in a high-handed manner. Most black people don't know how to handle it, so they're quick to lose their sh!t. White people LOVE this because it plays into their superiority complex. Me, I have this air of smugness that defends against such petty sh!t and this really irks them. I can go toe to toe with even the most passive agressive Stepford B!tch. They don't feel like better people around me. They feel like sh!t.
They totally lose their sh!t and start hurling out the racial sh!t in an attempt to level the playing field and get me to lose my cookies as they did theirs. Doesn't work. All that's left is a white person SCREAMING the N-word in pubic. No white person wants to be that guy. It's a really harsh cerebral blow.
I love asking white people "Do you feel better now?" after they drop it. It's funny how red their faces get.
My favorite target is white women. They breakdown in tears and totally lose their sh!t. White men are fun... but they have been getting WAY more violent these days.
