^But why?
I know some satanists who are absolutely the nicest people I know. They go out of their way to help people.
Just because someone differs in their beliefs, you reject them?
That's like me saying, all of you are wrong, I'm right, end of argument, there is no God, and I reject you all.
I think you could reject someone else's religion, but you should reject it more so for their actions and earthly beliefs, rather than just rejecting something because it differs from you, or is the opposite.
