Freddie Phelps and his kin?
Even Freddie hasn't tried to kill those he hates - he just bans them all to hell, along with the rest of the country and the world.
In fact, just once I'd LOVE to see Freedie get violent so that the cops could finally put his sorry rearend in prison.
Thing is, as much hate as Phelps is able to bring out of normally non-violent sane people, if he did take a swing at someone, he may not live to see a courtroom.
