It's the same position you're taking on Buddhism, which ironically, by definition are also atheism, with the only difference being that Buddhists don't give a rat's ass what everyone else thinks, while many atheists spend their time hating on people they never even met based on their belief system.
Have you ever met a Buddhist that's actually a bad person BECAUSE of Buddhism? I highly doubt it, I don't think you even actually met a Buddhist, good or bad.
Oh, and Buddhism actually encourages observation, research and science, and actually changes fundamental sutras if they were proven harmful or wrong. Buddhism isn't even similar to any other religion out there, I mean, there's no deity, there's no praying, there's no hell, you're not bound to do anything...it's just a guide to encourage people to keep seeking the truth, and live happier lives.
Same logic can be applied to the Buddhist governments Hitchens was referring to, just saying...
Tell you what, go read up on Buddhism, then get back to me, because you clearly have no idea what it's about (or just believe whatever your atheist heroes tell you, makes no difference to me). Though I will say that life's too short to spend it worrying about what others (especially those you've never met or will ever do, and will have no effect on your life whatsoever) believe in, instead of enjoying yourself. Your choice.
As for proof, go to Japan, and find me one normal person there....
Or just continue hatin, makes no difference to me, have a good day.
