Christians, as well as followers of other religions try to push conformity to people outside of their religion, not because they want to, but because God wants them to. It says in the Bible that we (I'm a Christian, so this obviously refers to followers of Christianity) should help anyone and everyone grow closer to God. If you don't want to believe, fine...But what are you going to do when God comes (I'm saying when, because I believe the Rapture will happen)? You can't just say "I believe" and get a one-way ticket to Heaven.
I don't even know why I'm posting this when no one will provide an argument back besides 'God doesn't exist, you can't prove anything.' You're right, you can't prove He exists, but you can't prove he doesn't. It IS based on belief, which is why the reward for believing is a great one (Well, that's all opinion of the theists/atheists). Most followers of Christianity say that faith is a test, and it is, because you have to believe in something you can't see, hear, feel, etc., which is a challenge when life is full of times you just want to say "fuck everything." I'm just sick of atheists acting like they're the shit because they refuse to believe. I'm not saying you have to, but when you put down my religion, as well as any other religion out there, that's a problem. Most of my friends are atheists, and half of them don't even know what the hell the word means. Compare religion nowadays to earlier times. It was abundant back then, because people didn't have music that pushed them away from theist beliefs (The people I know in real life that are atheists listen to metal, death metal, etc...The kind of music that people used to associate with Satan when it first started appearing), books that had other people portrayed as gods, and the list goes on...
The point is...I don't care if you're atheist, just don't bring down my religion...Atheism is a belief that spiritual beings don't exist, where as theism is a belief that spiritual beings do exist. Either way, you believe in something.
