Gays in the Military--What's the Problem?

The long-festering issue of gays in the military has again surfaced. And I still haven’t heard anyone explain in simple direct language what the issue is. I can imagine several fears, which get expressed as issues:
One is that some straights (I suspect those with fears of their own possible latent homosexuality) are simply uncomfortable being around gays.
Another is the fear that straight guys will be assaulted by gays in their beds or in the shower.
Another -- perhaps the one behind the resistance by some congressmen -- is the conviction that homosexuality is a sin, and we shouldn’t place these sinners side by side with our virtuous straight men in the military.
And the final one I can think of is the fear of the “homosexual agenda” -- the belief, related to the point above, that homosexuality is a (sinful) choice, and that homosexuals are trying to “convert” straights to be homosexuals.

These last two are matters of ideology, unsupported by any of the research on homosexuality. Medical science is emphatic that homosexuality is a condition, not a choice. And there is no evidence that homosexuals could, or would want to, “convert” others to homosexuality. In my experience, homosexuals want just two things: fair and equal treatment and acceptance, and, perhaps, the freedom to speak to encourage latent or “closet” homosexuals to accept their own homosexuality (which is not at all the same as trying to turn heterosexuals into homosexuals).
As for the first item, I think that is much the sort of thing that was said when the question of racial integration of the military was first considered: “Our boys wouldn’t feel comfortable having to associate with colored soldiers on an equal basis.” I’d say, “Get over it.”

What about the second item, fear of being assaulted by a gay guy in bed or in the shower? How about putting that to a scientific test? It should be fairly easy on a statistical basis. There are some reputable estimates of the number of gays currently in the military under the present “Don’t ask, don’t tell” policy. And there are specific numbers of gays who have been discharged from the military since that policy was imposed.
I assume that if any of those gays were discharged for making homosexual attacks or advances on straight guys, that fact would be documented. And of all the gays currently serving without being identified as gays, they presumably have not attacked or made advances toward straight guys -- or they would have been discharged.
So where are the numbers? How big a problem is this? I suspect that the facts would make clear that it is a vanishingly small problem. All the news reports I have read on the subject mention gays (something like 1300 in the past year, 12,000 in the last fifteen years or so) who were discharged either because they themselves admitted that they were gay or because someone else reported them -- but none of these reports that I have seen mention gays being reported for making advances toward straight guys. More likely it was because someone observed some sort of sexual contact between two gays, or -- who knows? -- overheard a sexually explicit conversation between two gays.

I think it is fair to note that, according to published reports, a woman in the military has far more risk of sexual attack from a male in the military than a straight male does of an attack, or even an advance, by a homosexual in the military.
