I like that it's "#1 racist" not "most racist".

Tritone is my #1 racist. And it's because I think that the others mentioned feel strongly about the stereotypes they post but don't necessarily believe a person's skin color really makes them inferior/superior, it's all about stereotypes. For instance Jigaloo's racial attacks are not about white superiority, they deal with stereotypes.
Tritone really seems to believe there is something special about white people. Unlike the other posters tritone's racism has no detectable sense of irony or sarcasm, it seems really serious.
