When straight soldiers do it to gay ones, though, well, that's different

As the times and the demographics swing away from them, the haters get apoplectic. Here's FRC's Tony Perkins (his emphasis):

As a veteran of the Marine Corps, I believe the President's timing on this issue shows he is willing to jeopardize our nation's security to advance the agenda of the radical homosexual lobby. We can't let that happen.

Our military exists to fight and win wars, not engage in radical social engineering. Forcing soldiers to cohabit with people who view them as sexual objects would inevitably lead to increased sexual tension, sexual harassment, and even sexual assault.
