No they are not discriminated against. I am a Christian and think God is great and everyone should have faith in Him. I know that many Christians here in the U.S. would try to spread the word of God to atheists but that does not mean they think differently of them or dislike them. God says that no human should be shown disrespect so any Christian that would do that is a false Christian. And Marcel no human can fix all of his or her problems/mistakes, but you can ask God for forgiveness and know that He will always forgive us because he sent Jesus who died on the cross for our sins. And if you are so proud to be an atheist I am sorry you don't know the righteousness of God and Jesus... I do not think differently of you or hate you because you might be a very nice and good human-being
