How do you figure? They are not born sterile, they are physically able to perform as soldiers in combat. Are you sure it isn't your own "politically based, and therefore, it's crap" view that leads you to such a conclusion? Discipline, good order, and morale all say that gays should not be a part of the military.
That may have been true even 15 years ago but if you read the article it doesn't appear to be a problem in our modern military. Society seems to be progressing beyond the paranoid view of leering homosexual ready to bugger you in your bunk.
Gays served before "Don't Ask, Don't Tell" and have been serving since and yet, somehow, our forces are performing well except for those who commit murder or abuse prisoners like those undisciplined homosexuals heterosexuals Charles Graner & Lynndie England at Abu Ghraib.
That unique policy, borne of Clinton's political cowardice has made things worse, not better. We can thank Colin Powell and the 1993 Democrat-led Congress for it.
I've long said, go forward to *open service* or go back to the outright prohibition. Looking at the list above seeing Saudi Arabia, North Korea, Venezuela and others on the prohibition of gays list makes it unpleasant for the U.S. to be identified with such nations.

The biological issues will drive the morale issues.
