guess who's coming to dinner (1967)

"The only thing that matters is what they feel, and how much they feel, for each other. And if it's half of what we felt - that's everything. (...) There'll be 100 million people right here in this country who will be shocked and offended and appalled and the two of you will just have to ride that out, maybe every day for the rest of your lives. You could try to ignore those people, or you could feel sorry for them and for their prejudice and their bigotry and their blind hatred and stupid fears, but where necessary you'll just have to cling tight to each other and say "screw all those people"! Anybody could make a case, a hell of a good case, against your getting married. The arguments are so obvious that nobody has to make them. But you're two wonderful people who happened to fall in love and happened to have a pigmentation problem, and I think that now, no matter what kind of a case some bastard could make against your getting married, there would be only one thing worse, and that would be if - knowing what you two are and knowing what you two have and knowing what you two feel - you didn't get married. Well, Tillie, when the hell are we gonna get some dinner?"
