Nothing he said there is incorrect. Nothing can be argued against, because all that he says is true. The only thing that I would fault him on, if he could be faulted, is that one has to remember that you are addressing other human beings, who despite their weaknesses, and their gullibility, are still deserving of some respect, just because they are human, like he is. So though his making those comments on youtube, usually in response to someone arguing against him, is quite appropriate and okay, he might want to be a little less caustic if he was at a social gathering with others who he hoped would invite him back a second time.I feel if I respected that I'd be needlessly contributing to the stupidity and ignorance of the human race, and that is one thing I don't want on my conscience. No offense.
Many people take attacks on their "beliefs" as personal attacks on them, as we see daily here.
