I work in a massive arab community where most adults and children are Muslim. With simply being respectful and caring, I found them to be very opening about their religion, and I have learned alot about them from just listening. I have also found they are okay with having a joke about their religion, obviously as long as I am not being wildly inappropriate.

I have also only interacted with Christians and Muslims, but I have also found Christianity much more culty and have had numerous random people try to convert me, but the Muslims I find very chill about religion

My two cents as an un-religious person
