I don't judge mania, or schizophrenia. But at what point do you stop trying to separate "the person" from the things they believe and say? He's a schizophrenic, and I can't hold that against him. But a racist, homophobic, antisemitic schizophrenic is just an asshole with a regrettable mental illness.
A quote from the "poor misunderstood" genius:
The IRA beat Sherlock Holmes with the grace of God. Ghandi was a faggot. God said boys should be taught military things.
Reputation is worth more than gold. Niggers have a reputation -- no fathers. Irish have a reputation. Germans have a reputation. Attacker has the advantage. Jews have a reputation. God said the French once stood for character. (Code of Chivalry) Ironic. I guess Jews did, too. Woah! God is boss. Too bad the Jews were cowards and didn't assassinate NAZI's.
