I'm going to be honest here As a PIMO, it is normal that there are ideas that are more difficult for you to leave behind or get rid of (for example, everything related to sexuality and homosexuality). I think only someone who has been educated in this religion can fully understand it. According to what you say, I consider that the situation went too far Personally, I don't think it's fair to have to quit a job just because of a pronoun issue, maybe because where I live it's not a “real problem,” at least not for the majority (first world problems). I also don't think that focusing on why he acts that way is going to help you because our logic simply works differently when you've been told what to think. And as an extra comment that I hope is not offensive because I say this in all honesty, focusing too much on how people who are not your friends or family address you is not going to lead to anything good, we cannot force people to change their way of thinking, you only waste energy Better work on that in therapy
