Being raised a Witness has a huge impact on my answer to the question. We were raised beleiving that brothers around the whole world were our own brothers and sisters, so as long as they were a JW, no problem, race not an issue. I do remember my mom saying, "It's okay to marry a black man, just know that you will have lots of problems with people being prejudiced toward you." It was true at the time, us living in a small rural Southern town in the early 80's, but now, I think it's much more acceptable, especially in big cities.
Funny, a friend of mine just came up for a visit. He's from my area, and was doing some work at my old high school, and he said he has never seen more interracial couples than at any other high school. I was kind of proud of that. My little town has come a long way, I guess.
When I stop to think about it, I have dated equally people of my race and of other races. 50/50. But I married someone of another "race" I guess you could say, though I really don't think it plays much of a role in our marriage.
