I believe where it is SAFE to do so, transgender people should be out and proud. And where it isn't safe, they should be proud if not out - and they should still work for equality, dignity and human rights so that they - and the generations that are to come - one day can be out. Nobody cares about people they don't know about, folks.
When people don't remind folks that they really do exist, the haters, purists and bigots like to believe and pretend that they don't.
