That's just foolish. As an Atheist I can not understand how any supposedly rational person can believe such utter nonsense as religion.
See silly insults can go both ways. I don't begrudge anyone their faith. And as long as its harmless I even encourage it.
Actually, it wasn't meant to be an insult. I've met and/or seen online a number of atheists whose essential argument against "religion" is that because something bad happened to them when they were a child, often something fairly trivial, therefore God cannot exist, because otherwise He would have stopped it from happening. Often sounds more like an excuse, than anything else.
