Look, I've already said I don't care about whether or not someone is gay. I care that they keep it to themselves while serving in the military, especially when the focus isn't on their sexual preference... it's suppose to be on the mission. So what's the agenda here? Why would it matter to gays if they can already serve but just cannot be open about being gay? The military doesn't actively search for gays who are serving; like it says, "don't ask, don't tell." It's a two-way street.
To answer your question more specifically ...yes, it would make me more uncomfortable if I knew I was showering and sleeping with gay men rather than consider the off-hand chance that maybe someone I'm showering or sleeping with is gay but not openly.
