Atheists, tell me, a Roman Catholic: why should I become an atheist?

[Whateverist]

I've seen that video here before on a number of occasions, and to me it's just silly. No offense Ben.

It's making stereotypes and assumptions about all people of faith. I for one, don't care in the least if someone doesn't have the same views on religion/God as I do. Obviously I think it's a good thing if someone does, because I believe it's the truth, but I most certainly don't feel personally offended by it if they don't. Believe what you want lol. So to me, watching this video is like, "Eye roll, these folks are way off and making the assumption that we're all immature, shallow, and stupid. How typical."

Ironically enough I've seen more people here who have felt angry that I believe in God than I personally feel towards those who don't.

I believe you (the part I bolded).  But you're not very representative among the believers we get through here or know in RL.  That is what makes you especially nice to have around - well, one of the reasons. (I think quite a few are also charmed by your poop obsession.) Likewise there are plenty of us who don't feel angry over what people believe, some of us are even intrigued by it.
