Hardly the case.
BTW, I am not sure I'm at all decided about the best course with this. I think however that eventually a repeal is inevitable.
I also don't think it needs to be a logistical nightmare - but I could see it becoming one.
I talked to two colonels (army) in the last week. When DADT came up it, they seemed to shrug:
"The army I joined isn't going to be the one I'm leaving, and the army that the recruits are joining won't be the one they leave either. That's military life." (paraphrase)
Admittedly, and somewhat embarrassingly, I'm not above having some prejudices against a repeal. But at the same time, I haven't found a well-honed logical reason for not resolving this.
