Different lifestyles

So I’ve been dating my BF since February and it’s going really well. We really mesh well. I have two kids that I had via sperm donor and he has none but is fantastic with my two. The issue I am having is that I grew up a non hunter. I have a very very negative opinion on hunting and guns and want absolutely nothing to do with it. I have friends that are hunters and it does not bother me talking to them about their hunts but my BF who is an avid hunter I instantly become angry whenever anything hunting is mentioned. I’ve told him multiple times how I feel on hunting but it’s very important to him and he wants his kids to be hunters. I’ve tried so hard to understand it and find some way to think positively on it but I just can’t. I get angry and inpatient and it effects my mood for the rest of the day and even makes me short with others and my kids which is not a good thing. I am trying to find a happy medium for the both of us to coexist peacefully on this subject but can’t, if anyone has any ideas I’d love to hear it!
