My few run ins with religous folks have all been rather nice so far.
This is a terrible method to understand the moral character of a person. You can exchange as many minor pleasantries as you want with people in the Bible Belt or Saudi Arabia, as long as they don't know you're gay, trans or want an abortion.
Why am I strongly against religion? Because it's a social institution that encourages trust based in faith, which is pretty dumb by itself, but I have also been shown again and again that sooner or later there will appear a bad actor with the clear intention to exploit it, and when the victims of their abuse try to denounce it, they will more likely than not find themselves kicked out from their own community.
To answer your question, the role of religion as an institution in my life is none, first because of the damage they have provoked on me, and second because I now actively try distancing myself from it.
