It used to say gender expression and identity. If it doesn't, that's a deliberate decision that could cause enforcement calls like 'well that's not your REAL gender so this isn't harassment'.
I mean.. It's already over-specified compared to others: "sex, gender or sexual orientation". It'd be equally right to criticize religion for why don't they write "belief, spiritualism, religion", and to include identity, and expression.
They should just write "sex stuff", and everyone is happy.
gender isn't sex stuff though, but thanks for the implication that i'm some kind of weird fetishist for being trans. you seem like an informed and reasonable person and not at all like someone who's completely clueless about queer issues and just spouts off whatever ignorant ass knee-jerk opinion floats through their head without an ounce of critical thought.
