There are some very committed and intelligent racists in the military and the police.
Please introduce me to them. I'd love to meet them.
Trust me, if you want to get ahead in the police or military in 21st Century America, you're better better talk-the-talk and walk-the-walk of multiculturalism.
If they're there (and I have no doubt there are racists in all walks of American life) they are so far underground that they might as well be cultural sensitivity trainers.
An overt racist in any major police department has as much chance of rising to a senior rank as a gay, Jewish, Black, transgender woman has of becoming Grand Dragon of the KKK.
