Nobody concerned about color, ethnicity, or sex??? You have no idea what the hell you are talking about. Here is some history for you. Back in the mid 90s, the O-4/5/6 promotion boards were given the following instructions: "Special consideration should be given to women and minorities for possible past discrimination." Think about that for a second. Genetics as the deciding factor and not actual discrimination but possible discrimination with the penalty being imposed on those that didn't commit any discrimination. Can't remember all the numbers but I do remember the O-4 board had a 94% promotion rate for minority women with a 73% promotion rate overall. Several lawsuits were filed but the O-6s, all white guys, were the only ones that had enough damaging data to cause the AF to settle out of court.
Nobody cares? A lot of people care and have no problem throwing the sex/race card to get what they want, combat effectiveness be damned.
