And it's not as awful as it sounds. Similar sorts of things happened at the co-ed school after I left (I still communicated with some friends there) but girls could still do thinks like manual-ed, even if they copped a lot of sexist flak from the boys for doing it. A gay boy was expelled after he got into a fight with a straight boy who baited him with homophobic insults (straight boy was allowed to stay, though). Girls still couldn't wear slacks, though I don't know if they tried the bra regulations (which never worked at the single-sex school I went to anyway. I still wore purple bras ;) ). There were as many/more sexist things happening at the co-ed school as there were at the single sex one, and in both it was perpetrated by the students and the staff. I just think those sorts of sexist examples that occur at most single-sex school are far less damaging than the kinds encountered at co-ed schools by most students, but that doesn't change the fact they are damaging (it can get pretty horrible at single-sex boys schools in my area).
