If I didn't already know you're European this would've given it away.
"There must be a reason for this retardation" is what people who don't have to be around blacks think to rationalize their behavior. Even liberal Americans wouldn't suggest this. They'd claim it's not enough educational resources or something.
You'd have a point if rinsing foodstuffs wasn't a common thing in a lot of Third World countries, where they actually have valid reasons for doing so. If I couldn't buy my groceries from anything but a disgusting New Delhi type bazaar, I'd make damn sure to rinse every fucking thing.
I'm not sure how you interpreted my characterisation of American niggers as basically retarded to be glowing praise, but I'll chalk it up to me not having your esoteric, Dian Fossey level of understanding.
"people who don't have to be around blacks"
I fucking wish.
