Everyone is insecure about something. It's weird because race is just a social construct. For some reason despite all that, we think people with certain skin colors belong to us. It's primitive but people do it. Don't let those people get to you. Just ignore them because they're on the wrong side of history. Walk with who you want to walk with and be with who you want to be with.
@Asker Most white people don't really care to engage in interracial. Most of us are quite happy dating our own white men/women. And from my experience, white women tend to be the best partners. But hey, keep hating on whitey. It's funny to see you fail.
Honestly, I don't think it's the white women that are insecure, it's the freaking colored women on GAG that keep asking these questions all the time...
