C'mon on now...Your only problem is with the folks who are disobeying DADT. That's not a reason to keep DADT.
There are plenty of gay folks in the military who are keeping sexuality to themselves, what of them? There are plenty of potential recruits who are gay that have yet to register with the service. What of them?
Can you please explain why DADT is a good policy to keep? What is so important here?
