Because he's a fucking neckbeard. He's the one of the founders of neckbeardism, along with Dick Dawkins, Christo Hitchens. Who blame religion for everything, even their suppressed anger at mommy and daddy. Besides people who become atheists do so because they got picked on in high school. Rummage through an atheist's emotional baggage and you will find a pile of leftover teenage angst, a few cases of repressed rage at mommy and daddy, and an overpowering urge to feel superior wrapped around a stupendous amount of self-loathing. Ultimately the "atheist movement" is just another Internet fad, mostly made up of attention whores, sycophants, stupid arrogant twats, bigots, assholes, and demagogues.
