Atheists acting like Theists

I’ve noticed there are some very common things that theists say on this site, that would never ever be used in the opposite direction. The crown jewel is if I were to say:

You don’t really believe in god, you just don’t want to sin. Also, my book says that everyone is without excuse and knows there is no god.

I would never even be tempted to say something so arrogant. I would never tell you that you don’t really believe in god. If I’m having a conversation with one other person, I will always defer to their far superior knowledge on what they believe… because how the hell would I know? And yet some (not all) theists do this often. To the point where I would classify it is “extremely common” to be told that I know there is a god… I just want to sin. No, I don’t.

If you’re not an atheist, then why do you talk about it so much?

The only reason you’re religious, is because something bad happened to you.
