Those are great points. I think many of us, regardless of color or ethnicity, tend to hang out with those most like us in our personal as well as our professional lives. As a retired military officer, I have much more in common with other current and former military people no matter their cultural background, gender, even nationality. I find I have less in common with whites like me who don't understand that experience and can't share in the shared sacrifice that bonds military people. Military people understand and accept each other in an unspoken way. I believe the same is true of athletes and many other groups. I know football players who prefer hanging out with other football players, regardless of black, white, whatever. Same with musicians, car guys, etc. People like to be accepted for themselves.
