Maximum feasible wackiness.
He begins the program asking how it could be that the atmosphere of hate created by right wing hatred of Kennedy could have somehow prompted a leftest like Lee Harvey Oswald to assassinate the president. But isn't it more likely that one had nothing to do with the other? How can the right wing get blamed for acts of violence committed by people on the right that don't happen and also get blamed for acts of violence committed by people on the left that actually do happen?
Later he says something to the effect of how should we deal with people that call people Nazis and compare them with animals? Now I didn't much mind it much at the time, but I remember the Bushitler stuff starting pretty early on and seeing the "Bush is a Chimp" side the morning he was elected. I must admit the last one was pretty funny.
