What a bunch of weasel words.
When you set up a community where people can effectively "vote" you out, which is what they've got, discrimination will be RAMPANT. People will happily vote anyone out who doesn't match the mainstream - different religion, different race, and yes, different gender identity.
Adding a gender identity marker is a TERRIBLE solution. Kind of like the pink triangles people were forced to wear during Nazi times. Now you'll get voted out unless you clearly state your gender history up front.
Stephanie, thanks for posting this. I hadn't heard this, but I hope trans rights group give them the butt-kicking they deserve.
