Religion is not an issue for me.
I have no objection to anyone's religion as long as they respect my freedom not to have their beliefs forced on me. I have friends of several ideas; when I make friends, religion is not put in the equation as I have friends whose faith I have never known.
I never knew about their beliefs because the topic of religion didn't come up in our conversations.
Peoples sexual orientation is another thing that does not bother me for the same reason.
