Good point. To add to that, another thing about the "if you don't like it you can go back to Africa" argument. It was people like the ones who would say that, whom brought black people here in the first place.
There are two kinds of black people in america today, The ones whos ancestors would have liked to go back to africa given the choice, and the ones who moved here on their own accord to make a better life for themselves. Both, are americans now. They vote, pay taxes, work, eat, sleep and shit like the rest of us.
Maybe our Gov can find some funding for the "Find the racist MoFo's an island to ship them off to" commitee. We can find an island somewhere in international waters. Biggot white, black asian, whatever; can be sent to this island where they can learn to get along, or kill each other. Either way, problem solved.
