It is a private school they can have the students they want or don’t want.
As far as “gay” issues with students go, I wish we had don’t ask don’t tell for students. I have heard that for girls especially, they can go through phases in which they think they have attraction to girls. But then they grow up to be normal heterosexual women. It might be a good policy to just say, we’re not going to talk about sex orientation of students, because students aren’t yet adults. They aren’t yet finished growing up.
If these students really feel the pull of “gayness”, when they are of legal age they can head on down to The Castro and explore things to their hearts content. If their bodies and minds are still developing, perhaps their “sex orientation” is also still developing, and shouldn’t be disturbed. I guess the gay activists would have society apologize for having social norms that might push people towards heterosexuality, but that’s their problem, not the problem of society.
How did civilization survive all these many thousands of years without giving such special treatment to the homosexual community?
