if you can't respect that, please leave.
or, at least, respect that this is a safe space and posting discriminatory content isn't cool and does not fit under the banner of "Safe Space."
i know a thing or two about safe spaces and doing stuff like that gets you banned from them in every other instance of their existence. (i volunteered in a LGBT Youth Center, for one thing, and it was kinda a big deal because those people really needed that space to get away from mean spirited people; it's sort of terrible to go into that safe space for those people to feel safe and welcome and then to tell them they suck, like the rest of the world pretty much already does)
there's no courage in telling a group of people they're wrong about something very personal and integral to themselves
it's really just mean and you don't really have the right
so don't do it.
