Khanzumer, as I've told you via PM, you weren't banned. If you were banned, you wouldn't be able to sign up with a new account as your IP would have been added to the ban list, not your username.
One possible problem is that your cookies are playing up. Try clearing your cookies by clicking
here, then try logging back in with your old account. If that doesn't work, or if you're presented with an error message, please tell me what that error message says and I'll do all I can to help.
I'm very sorry you've had difficulties with your account, but be assured we'd never ban someone for their religious beliefs.
