I really think the older service members, the ones in charge of things, don't realize how few young people care about who is or isn't gay. There are plenty of pretty-much-openly-gay service members, and hardly any complaints from heterosexual service members about living with them. In his many years of service, my husband has never heard such a complaint from any of his sailors.
On the other hand, the Marines have the worst living quarters of any of the services, so it wouldn't be a bad thing to build more barracks -- the whole gay-segregation thing will go away pretty quickly. (For one thing, trying to have the correct proportion of gay and straight Marines in each unit to fit the housing situation will not work), and they'll be left with more and newer barracks. Or, if the plan would be to give everybody private rooms, well, that's win/win.
