Atheists angry at Tebow for praying! How shocking! Wait, no. I mean how hilarious and freaking typical. Complete, of course, with the "an atheist lectures Christians on how to be Christian with a bible quote, mangling the understanding in the process" routine.
Of course, they also know for a fact that Tebow is just trying to look pious. He's "totally faking it". You couldn't make atheists look more petty, self-absorbed and thin-skinned if you drew a cartoon featuring them.
So, in honor of the move, let's return the psychoanalysis. As ever, these are not mere irreligious - they are anti-theists. And the idea of a celebrity being not only Christian, but publicly so, bothers them. They worry that maybe this will inspire people to be more public with their faith, or worse, to spread it. So they desperately want a forum to rant about it, to attack. But since, as Vox Day notes, self-described atheists tend to have a severe case of social aspergers, they just come off looking so damn bad.
Leave the attacks to the people with skill, Cultists of Gnu. Trust me: you guys are at your best in the dark, in the basement, on the computer and massing in some poor guy's comments section.
