I've been reading this thread with a certain amount of interest, and I have to admit to being impressed/surprised that for the most part folks have kept it from getting personal. For myself, I don't see this as a big deal from a readiness point of view, and I just can't see the Navy having nearly the same amount of growing pains as we did integrating women aboard ships. First of all, I think we are dealing with vastly lower numbers here. Even if you took Kinsey's number of 10% of the population being gay - and I wouldn't as a quick google of more scientific surveys seems to suggest less than half of that - there is a further self-selection issue that our all-volunteer force puts into the equation. The gay folks already in the service have demonstrated an ability to get along with their straight counterparts at least well enough to have survived DADT up to this point, and at the risk of stereotyping, the all out flaming drag queens that some people in this thread are concerned about probably aren't all that interested in joining up. Secondly, pregnancy is a huge readiness issue aboard our ships (though it does keep the gedunks and pass/tag offices well manned for shore commands) and if I understand the process correctly that isn't going to be a problem with repealing DADT.
Having said the above, is it possible that an activist with an agenda could make it through the enlistment process, then through boot camp and initial schools, just so he could arrive at a ship and act out in pursuit of some gay agenda goal that I can't picture at the moment? I suppose, but that risk is small enough I'm not going to lose any sleep over it. Are gay activists going to move on from this fight to the gay marriage fight? Probably, but I don't care about that and it isn't going to be the military's problem - Congress or the courts will decide whether or not the military has to recognize same sex marriage.
Other issues, and the ones that seem to have sparked the most debate within this forum, are the questions of people's moral objections and comfort levels. For those with moral objections, I've got nothing to offer. Since I personally can't give a rat's ass less about a fellow service member's religion, sexual preference, tv watching habits, etc, I recognize that I lack the ability to show any empathy to people's moral objections so I try to stay out of those discussions. For people with comfort level issues, they will have to decide if their objections to serving with gay's in close quarters out-weigh their desire to stay in. If that is the case and you feel like you have to get out as soon as your obligation allows, then thank you for your service and no hard feelings on my account.
Overall, I think that in 5 years the fuss over this will be gone, and by the time my son (now 4) might be able to join up no one will care anymore.
