I think that religion is dangerous pathetically sad and that believing in any religion makes you a less intelligent person
Are you being serious right now? What makes you believe that religion is stupid?
I knew people who have been brainwashed by believing in a god.
Well, it's fine of you to think that.  Just like it's fine of them to disagree.  Everyone can have their own opinion on religion!
If you don't care about religion, why are you getting you panties up?
While I don't care about religion, I do think that you shouldn't be judging people solely based on what they believe in. You don't know who is dumb or smart just because of their belief in God or a lack thereof.
