In my experience you donít even have to be dating them, being a white guy and just publicly seen with a black woman, and people automatically draw all kinds of opinions and bias.
Just remember god gave us two middle fingers. Sometimes one just doesnít make the point harshly enough.
A friend of mine and I were very close, she's also white and I look more black than not. When we used to go out in San Antonio to do things, we wouldn't even be touching and people would stare and look and sometimes just give us dirty looks. And its not just whites, don't get that idea. The worst were other black women, they would really seem angry or something some of the time. People would ask, "how do you know that's why?"
On two occasions she was in the bathroom and I was at a table in a restaurant. We had a female waitress, who was black and upon seeing me, she would seem chipper, happy and friendly. When my friend returned she would pretty much become cold and rude. When I pointed this out to my friend she exacerbated the issue by hanging off me, snuggling up against me and one time she kissed me.
Another friend of mine who is dating an Asian woman has had similar experiences.
