My religion's Atheism, not because Atheism's a Religion you understand, but it can be someone's religion in the same way that Religion can be someone's religion, even if they don't take it Religiously (I've known a few), unlike the Religious, who take their Religion very Religiously indeed. I'm not Religious about my religion because my religion isn't a Religious sort of religion, it's a very non-Religious sort of religion; in fact, it's the sort of religion that the Religious would have good reason not to find Religious at all, maybe a little sacrilegious, but sacrilege is cool because it doesn't take Religion Religiously but understands that it's going to be different for everyone anyway, and the trouble starts when people start take offence over other folks' religion be they Religious Religions or non-Religious religions.
