Let him spew his venom. It serves as a reminder that all is NOT sweetness and light out there beyond the boundaries of this forum and that we must all be aware of it every waking minute.
Racism and hatred flourish best when no one speaks out against them and their promulgators. If crap like this is pulled, then others are deprived of the knowledge that it not only exists but is doing its best to spread its corruption.
If you think this is bad, there are sites out there that would curl your hair. So spread the word. The hate-mongers and racists are among us.
