homophobic father issue

I'm gay.My dad is not pleased with this fact. Completely homophobic.Half the time his homophobia doesn't even make sense.Fishing show on TV in the living room Watching it with mom and dad Mom: "I don't have the patience for that kind of stuff" Me:"It doesn't feel like too long when you're out there" Dad:"Time flies when you're a faggot." Go to my roomIt's getting ridiculous. He goes out of his way to respond to everything I do by calling me a fag.What do I do?
