No one should be signing up for the military with the preconceived notion that some things in the military won't change while they are in. Every military member is expected to show enough discipline to not allow their personal feelings interfere with their ability to do their job, which is to fight or support a war. And if anyone is currently signing up actually believing that they will never have to serve alongside a gay person, then they are deluding themselves. Especially with the way the rule is written about who decides whether to even start an investigation into someone's sexuality. An individual cannot start an investigation into the sexuality of another servicemember on their own, so if there was someone who was openly gay in their unit, and the chain of command chose not to do anything, then they would have to suck it up and live with that person anyway. A person can testify all they want that they heard someone say that they were gay, but unless their is an investigation open into the matter, authorized by the CO, then that homophobe is clear out of luck (and yes, anyone who would turn someone in just for saying they're gay without any misconduct on the gay person's side, is a homophobe, since they are doing so out of fear that the homosexual person might do something).
