Does anyone happen to know if there's a word for this?

Is there a word for Religious Discrimination, like racist, hoặc sexist? I really need to know because I'm nghề viết văn a letter to someone on Fanfiction who thinks that Atheists are better than Christians. Both are equal in greatness. I just found it offending that he đã đưa ý kiến Christians are horrible and that Atheists are better, because both are equal in greatness, and I'm rambling aren't I? Anyways, I just need to know if there is a word... Thank you! Have a great day! *Waves at you.*
