Parents can only say so much, because at the end their kids go their own way. Yet... I would NEVER give my approval, if my kid wanted to date/marry a black, regardless of his choice of political party. I'd most likely disown my kid if they got with a black.
Such a stupid question. Who you vote for doesn't always define who you are. Yes, it says something about you, but not all. I'd rather he votes for Trump, but maybe the Hillary supporter, though having shitty political beliefs (in MY opinion), treats my daughter better than the Trump supporter.
Assuming both a great guys deserving of my daughter, I prefer the black Trump supporter. Not that I'm a Trump supporter, but he's better than Hillary.
