what would you do? this is long so thank you to those who read all the way through

I love my boyfriend, but recently I don't love how he is. When we got together 2 and a half years ago, I wasn't really aware of his views. I honestly think they were fine back then- more liberal but now they've became on the extreme conservative side. I don't consider myself conservative or liberal. I'm right dab in the middle, I see both ends. He's honestly become an asshole since this election started. He doesn't see the big picture and when he looks for things that only back up his view. He's extremely hard headed and stubborn and he was from the start but now it's ridiculous. He will interrupt me if we're having a debate about something and keep telling me that he's right and I'm wrong and will get really rude and won't stop until I say I agree with him which I never do, I stand my ground. He will even get into arguments with my mom because she's a Hillary supporter. I don't like Hillary either but that's my mom FFS. I can't help but say his views are very xenophobic, and prejudice. He's pro life, hates abortion and thinks I'm disgusting for being pro choice. He thinks Islam is an evil religion. He doesn't like any other country. He thinks BLM is a legit terrorist organization. Doesn't think rape culture is a real thing and doesn't like feminists. He's convinced lesbians aren't real but gays are!! He wasn't this extreme when we conceived our daughter and I'm scared to raise her with him. I don't think we will agree on things when she is older. Besides everything I mentioned, he is a great, loyal boyfriend and dad. He loves our daughter and though he doesn't really help out a lot with her (she's 3 weeks old), if I ask him to do something, he will. I don't know what I'd be without him. We've had a great relationship and I want to marry him but this other part of his personality is driving me away and he doesn't even see it
