[Caesar Soze]

The US armed forces officially began integrating in 1948, when Jim Crow still ruled much of the country. In that case, it really was a social experiment--the military was on the cutting edge, and the rest of society followed.

DADT is a different case. Society has largely made up its mind, and now the military is rushing (or being pushed) to catch up. (I'm using military to refer to the institution; the individual members are largely apathetic to sexual orientation AFAICT.)

[Recovering Ex-hippie]

The stats say there are thousands of gays serving in the military. We have women serving in the military.
The heterosexual women and men all have already been showering or bunking with lesbians and gays.

So, if we enforce the rules against anyone acting out sexually( male or female) and throw out anyone who does NOT act appropriately. how would this be different than what we have now?

Of course, the ideal would be to not have women or gays in combat areas or in country. But that will never happen cause of political correctness.
