The question is quite tribalist if you ask me and goes against everything I think of when it comes to being anti-theist or atheist etc. which is not to fall into dogmatic and tribalistic thinking. Of course you can make friends with people of all ideologies. Will you get along with people who mostly agree with you? Probably, but as far as our everyday lives, most of our friends and family are already theists so the question itself is quite stupid unless you just cut out everyone religious in your life. I personally chose to associate myself with people who agree with some of the core tenants I believe, but most people would believe most of them anyway. People seem very fickle and must have everyone in their life be their echo-chamber otherwise it's time to cut ties, it's pretty child-like, us vs. them, all or nothing behavior when it comes to other people.
If the hypothetical idea of an afterlife means more to you than the objectively true reality we all share, then you deserve no respect.
