Have you seen the problems in the mixed-sex units? I have. It’s unbelievable the issues that pop up when you mix men and women together, in close proximity, day in and day out under tough conditions.
Now, introduce someone of the same sex, but this person still wants to have sex with all of his/her buddies, and the advances are NOT welcome.
You’re telling me that will have no affect on unit cohesion?
I’m telling you from 20 years in the USAF, that having women (and homosexuals) in units under my command had NO appreciable effect on cohesion or morale. If you try to convince me otherwise, I place the blame squarely on unit commanders who tolerate it or quietly encourage it.
