A Big Ratio

Over at Instapundit, Glenn Reynolds says:

WHEN I READ STORIES LIKE THIS, I wonder how we're doing as well as we are in this war:
"U.S. military continues to discharge gay Arab linguists."

That leads me to ask, "How many can there be?"

I mean, if we are complaining that we can't find/train enough Arab linguists to fight the war, that means there is a only small pool of them. If that pool is so small, having 58 of them be gay sounds like it would be a pretty high percentage for a discharge-to-AFSC/MOS population ratio. I haven't the foggiest what that might mean except I suppose that statistics would portend there couldn't be many more of them. Perhaps is is because many of them go through more rigorous back-ground checks for security clearances.
