Why let people know? I'm not going to start up a match, and then ask the fireteam if anyone is gay/black/female/disabled/albino, and then judge them on that. There's no need to hide anything, but there's also no need to throw focus on it when it has nothing to do with the game. Can you shoot? Can you follow the flow of the game? Can you work in a team for the raid? If the answer is yes, then great. That should be the end of it.
