Beyond your wishful thinking here’s no reason to believe the American experience would be any different than other western countries’ experience has been.

You’re talking, I suppose, about military forces outside the United States. The possibility that non-American militaries might have allowed homosexuals to serve without obvious harmful consequences does not mean that the American military would have the same experience, if it went the same route.

…except for that tiny little inconvenient fact that none of the theorized disruptions have occurred in practice.

To think that your nation is saying anything at all about you as a person by passing the don’t ask, don’t tell law can seem a little egotistical.

That law, while it unfortunately does not go far enough in its restrictions on homosexuals in the military, does make perfectly reasonable points about military life, and the reasons it gives for thinking that the presence of open homosexuals would be disruptive are sound.
