Intergration was being slow walked until Korea. It was only fast tracked because of the need to pump replacements into combat depleted units. And I hate to tell ya but it didn't obliarate racism. Racism still exisists in both in your face and subtle forms.
Why? Because like anti gay sentiment it is a value set that is ingrained in some individuals. Yes the military has a better chance at stopping overt displays but it still dosen't control value sets. Your allowed your own values as long as you abide by the regulations and keep your mouth shut if your views conflict. But civvie side your pretty much can speak your mind as long as you don't resort to violence, it's free speech and it's protected in most cases.
Integration is actually a bad example although the PC'ers love it. Gays aren't segregated, this is just used to give the broader agenda a legitament look and piggy backing an actual legitament civil rights movement.
