This may be a comment that's a little extreme on the matter. But.. I wouldn't say it's a complete lie either.
I subbed for my areas cafeterias a few years back. Those ladies were racist, homophobic and they were more than okay with keeping a ton of religious objects and reading material in places where the kids could find them.
They might not be teachers.. but if their support staff is full of bigots, then I have no reason to hope that the teaching staff is any better.
We have to face the fact that the fight is not finished, the battle is turning, but it's not even remotely over.
