As a new atheist I made myself a promise. I'm having a hard time keeping it.

I told myself I wasn't going to be that guy that makes the your so stupid for believing in god comments. I go on Facebook and start reading posts and thinking This shit doesn't even make sense if you are a Christian. I mean come the fuck on some of this shit is just stupid. I'm starting to have a very hard time biting my tongue. How do you handle it?
