I watched it live over the Internet, and I kept thinking it HAD to be a crank. I think his "best" argument was that God had to exist because atheists say "I do not believe in God", but in order to say that, you have to say "I do", thus God has to exist! No, I'm not shitting you, he actually said that!

Yeah I heard that part. It was "Since you have to say 'there is' before 'there is no god', therefore god exists." Which really should have been the hang-up moment. If you look at this guy's other videos, he's pretty obviously got some sort of mental handicap/retardation. His preaching videos smack of an autistic person imitating learned behaviors and phrases. Obviously the atheist experience people couldn't have known who this guy is, but now that he's been outed, I honestly feel kinda awful that someone took this guy's childlike mind and fucking warped it like this.

That's Internet for ya.
