I peak transed a while ago, but then have leveled out recently and taken the live and let live approach in my thinking.
However this sign in a Scottish university bathroom, designed by transpeople, bothers me.
"they are using the facilities they feel safe in - please do not take that right away from them"
So if there's a petite young woman in the toilets beside a 6'3 muscular male appearanced person and she feels uncomfortable, where does she go to feel safe? The disabled toilet?
Also "don't challenge them" sounds wrong to me. Like they're untouchable. What if they're acting inappropriate?
