My black dad is racist

My dad is racist. I grew up with him for 17 years (now 32) and I know he hates white people with a passion. His entire facebook page is antiwhite. Its actually embarrassing. He won't even acknowledge my fiance who is white. Nevermind that he is successful, smart, and litterally the best man I have dated and treats me better than any man I have dated, my dad hates him b4 he's met him. Anytime I bring up my fiance, my dad changes the subject. It's really annoying. When we first started dating. My dad saw this on facebook and immediately demanded he know his ethnicity. When I said "white" he seemed dissappointed. You would think that it would be the other way around with my fiance parents hating me. I met them and actually spent a week with his parents and they called after to say how,much they liked me....

I posted something about how dumb it is for people,to protest after be given the chance to vote in the last election on my Facebook. Litterally 10 minutes later my dad calls, saying it's offensive and I shouldn't post it. Mind you his page is nothing but anti america, anti white memes and statuses. He even used to say to me as a kid " anyone who married white is stupid".

My dad is really getting on my nerves....how do I even deal with this? I have had to block him from commenting on my Facebook because he writes post like" all white people are evil"..... How was I born into this family??? How do I deal with this and still be respectful? I live in Florida and he lives in NC. Luckily I only have to visit during holidays. Lol
