My dad is white and my mom is Asian. As a U.S. GI, he married her in early 1946 in Tokyo, and they left Japan for the U.S. east coast a few years later. They decided to drive cross country and settle in SF. During the drive thru southern states, they stopped at a few gas stations.
My mom saw the "White Only" and "Colored Only" signs on the restrooms, and asked the locals which one should she use. The men there would look at her, an Asian, ponder it for a moment, then look at their own skin, then direct her to the "White Only" door.
That was a long time ago. Incidentally, my dad met a lot of resistance from Army officials and had to fight for the right to marry an Asian.
I’m probably sure that a lot of what your dad went through was because the war had only been over for a short time. Thankfully your mom and dad prevailed. They had you and did not decide not too have you as these people do now days. I know a lot of mixed race couples who went through a lot of crap, especially here in the states trying to find suitable housing etc around a base from prejudice people. I know that I can honestly look my face in a mirror and say that I grade people on how they act and behave, not on what they look like. Act like a decent human being and I will treat you the same in kind. Act like a complete ass, then expect me to treat you the same way. Good luck.
