I hate my in-laws

I really hate my in-laws and they aren't too fond of me either. I've been with my man 2 years in September and haven't had too many issues until recently. My in-laws and I have differing political/religious/social views and they are starting to make fun of me for it. And teasing my man about it over the phone. His brother is constantly making fun of my Latin heritage and I'm just fucking over it. My man says I should "earn my respect" by addressing these issues head on. But I'm just wondering why the fuck do I want to marry into this family? I have been nothing but motherfucking polite. We will be moving out of state in a few years and won't see them nearly as often. Is this normal? Can I have a fully functional relationship with my SO even though I can't stand his family?
