I mean, in terms of friends, I don't really think there is a political stance that would make me not want to talk to them...unless all they ever wanted to do was talk about that political topic. And then I wouldn't want to be friends with them because they're boring.
In terms of like, religious, I'mma go ahead and say I don't think I could be friends with someone who was seriously a Satanist. Like, call me old-fashioned, but there's just something a little off-putting about someone choosing to identify with the teaching of evil. It's like if there was a religion that supported I dunno, like punching kittens, puppies, babies, and hamsters. I think I'd be a little wary of someone that was like "well, yeah, I obviously go in for all that and I'm going to a kitten punching next week." It isn't just that they're harming another creature, it's that out of all the potential ideologies they chose that one?! What kind of person chooses that one!
I'll admit the older I get, the less time I have for the average le skeptic atheist. But, I'm still friends with a lot of them, I just don't see myself reaching out to get me more of those without the person being really really great. It's not even really their opinion so much as how they inevitably present it that makes me want to hit myself with a frying pan.
In terms of a romantic partner, I mean, I'm faithful, but not really religious persay. I suck at following the commands of my God, so I don't see myself getting all high and mighty about it. I know that I would prefer a partner abide by my wishes and not eat pork or shellfish. I know that I won't and I won't want it kept in my house. I don't keep sabbath now, but I'm hoping for that to change when it doesn't mean destroying my job and future ability to have a family so I would hope they would observe it with me. I would hope to someday convert that person, but I'm totally on board if they want to try to convert me too. That street goes both ways. I don't go to church and think it's a mockery of god's law and despicable.
So to me, there's higher virtues to seek in a partner than whether they agree with me on my faith. And compromising is a good skill to learn in marriage (or so I've been told by married people that don't hate each other and so my own perception of my parents who do hate each other and never compromise shows). Some people don't wanna compromise on this and I can theoretically understand that. It just isn't me. So long as my husband is kind, forgiving, loving, joyful, and hard working (hot af), I think we have an entire life-time together to work on what the other believes. In terms of children, I would like to raise them to at least know about my faith like my parents did, but I think it is something they should choose for themselves.
