Those opposed to to revoking make a series of arguements, none of them very good.
We are frequently told that it would be bad for troop morale and that we need to be sensetive to the feelings of the troops. Both of these arguements were made when the issue of alllowing black soldiers came to the fore.
If your morale is so easily damaged you have no place fighting in a war zone anyway. The old saying good players adjust comes into play here. Soldiers are old enough to carry guns they will deal with it.
As for being sensitive to what the troops want, if they wanted people to be sensitive to their feelings and respectful of their beliefs and ideoligies they should not have joined the military. The military is not a democracy. It is a top down organization with ranks where people are given orders and the President of the United States is also the Commander in Chief of the United States Armed Forces.
As for the final arguement that a gay soldier might see a straight soldier naked. So what? Do people really think that gays only joined the military after Don't Ask Don't Tell? Do we think that Gays and straights have not seen each other naked. The fact that anyone can make this arguement with a straight face simply proves they are a biggot.
Let me close with a quote from that great conservative icon Barry Goldwater "It doesn't matter if they are straight, it matters if they can shoot straight."
