How do you deal with a father that constantly yells?

I'm currently in my early 30s and my father still yells at me. In fact he yells at everyone, my mom, his mom, my brother, his sister, his brother in law. Feels like he just loves conflict. Since I was a kid I always avoided spending time with him and nowadays I avoid visiting him because I know at some point he's going to start yelling at someone and there's going to be an argument. I'm afraid one day he might yell at my husband. How do you deal with a mad person?
