Have you or someone you know ever been imprisoned for saying "nigger" aggressively at a nigger? If so, first of all thank you for your service in the Great American Racewar. Second, did you happen to notice the judge penalized you, like, at all? Due to a Supreme Court decision all the way back in 1942, it is currently not protected by the first amendment to say a word towards someone that is known to instigate violent acts.
The only idea I have is some martyr hangs around nigger bars until someone calls him a "cracker" or "whitey", act like a nigger yourself, then find a lawyer who is willing to take this current discrepancy in how the law is applied up to the Supreme Court. Then win the case and no guarantees there. Needless to say, this is a pretty bad plan, but it's a starting point to stimulate a brainstorm. Whaddaya got?
Side note: I noticed this in the first place when I wanted to learn what speech is not legal as indicated by the 8kun splash page
