I for one wouldn't even notice a trans*/genderqueer person used the lavatory alongside me (I'm betting there's more than one attending the college I'm at right now, and I have no clue whether they use the ladies' or the gents' loos). If they were all cubicles, I wouldn't care if all toilets were unisex (just like our toilets in our private homes) - I just object to the smell of urinals :D
