Family housing areas are on and around every single military base.
Homosexuals are something like 10 times more like to engage in molestation than the general population.

Xzins - massmike has a lot of info and facts at his fingertips; I don’t so much any more. But you are correct - the incidence of violent “partner” or domestic abuse and assault is much higher, promiscuity is through the roof, drug and alcohol abuse is much, much higher. Rape and molestation are of course much higher.
