Why can't Athiests respect religion?

I don't mind Athiests not believing in God, as it is their prerogative, but why is it that when I post a question on here concerning religion (and I seldom do, because I know what will happen) it is immediately pounced on and I am plagued with answers concerning the "irrationality of religion"? I know that I should not let this get to me, but it really is troubling. Just as you do not like the Church condemning you for your beliefs, I do not like someone all but calling me an idiot for having chosen to believe in God. Live and let live.
