Why is everyone always so fucking stupid?
You can be a Christian, or a Jew, or a Catholic, or whatever you are, without going to church.
You don't go to church to prove your loyality to your religion, you go to church to learn about it. If you don't want to go to church, that's fine, it's your decision, but that doesn't mean you have to become an athiest just to do it.
Do you think God wants you to live every day in preppy little dress suits, sitting in a bunch of pews, listening to the endless preachings of someone? No. He wants you to live your life to the fullest, doing what's right and being a good person, occasionally looking up and saying "Thanks."
