Drawing on his military experience, the Sage of Mt. Airy points out the dangers of the political correct (on environment, religion, sexuality) military to mission effectiveness. Peer pressure
works by forcing those soldiers whose principal concern is military effectiveness (and thank God there's still plenty of them) to simply accept the PC codes as part of the "given" in any problem they face. Political correctness is, with a "can do" shake of the head and shrug of the shoulders, simply accepted as one more obstacle to be overcome. The effective officer figures out a way to work around it.
But the way around it is always inefficient, sometimes dangerous and far too often dispiriting. My son is a U.S. Army First Lieutenant currently serving in Iraq. When I asked him about his training at Camp Shelby in Mississippi immediately prior to his deployment he answered with this: "Dad, I'm not sure how we'll perform in combat, if and when we engage the enemy, but one thing I do know, we'll sure as hell not sexually harass them."
Now I suspect some of you may think I'm overstating the case. If so, ask yourself this question, or better yet, ask it of anyone you know (male or female, straight or gay, white or not) who holds a position of command in the military, at any level of responsibility: Is their duty of disciplining a poor performing soldier complicated or simplified if the individual in question is a straight white male? We all know the answer to this.
