Self Chosen Slippery Slopes

In response to this article, I want to ask one question...how does this change the landscape of tolerance in public schools?

I understand that it might be better for these students from a safety standpoint to be in a school with a peer group that is fully supportive of their lifestyle and orientation, but something about this doesn't sit right with me.

If we suggest as a city (Chicago) or as a country, that we should group gays, lesbians, and transgenders together into one demographic of a high school, doesn't that mean, while confrontations and safety may be higher, exposure to other viewpoints and other individuals will be lessened?

I can't help but wonder if my close friends that are gay/lesbian/bi-sexual and transgender decided to go to this public school instead of mine, i wouldn't have been offered the chance to get to know them so well and become such good friends with them. I can respect a decision based on the safety of students, because that is supposed to be one of the most important things a school provides, beyond the "education" factor that is a given. But, what about the whole diversity in schools idea?
There are a lot of high school students out there as it is, that will not meet an openly gay/bi-sexual/transgender person until they get to college...(remember small towns in Iowa are rarely the bastions of liberal ideas/thinking that the state as a whole may be thought to be) and that may be okay for many of them, but I'm sure they often wonder if someone in that school has a different sexual orientation and just hasn't come forward.

I am for people being comfortable in their skin, and if an openly gay/lesbian/bi-sexual/transgender high school will allow that to be the case for some folks, then I'm for that aspect of it...but I can't help but also see this as leading down a slippery slope of self-chosen separation, which will afford few high school students the chance to change their views on certain aspects of the culture/community of GLBTG folks or vice versa.
