Rates of Homosexual Assault in the Military Are Disproportionately High
I agree with that. I just don't know the answer to keeping them out. It's like gun laws: only law-abiding citizens obey them. Criminals don't.
Say we ask everybody who signs up, "Do you like to perform homosexual acts?" Some bugger who wants to be in the military might lie and get in. I'm not saying we shouldn't ask; I'm saying it's not effective. Discharging those caught in the act is 100% effective: the problem is removed, and there is an example set.
