@ehBeth,
I'm wondering if the reason for this might be 1) to avoid pointing out specific students that may not be "out" and 2) to avoid having those that may seem "flamboyant" or "artistically inclined" or whatever other term often gets applied to gays, tagged as specific to that group when some people are those things without being gay.
I don't question your judgement of the situation, Snood. You're there and I'm not. Just wondering if there is some protection of the gay/lesbians taking place by not addressing sexuality specifically. I mean, if someone is black, they are black and most people know it. If someone is Hispanic, it's kind of obvious. But, some things aren't as obvious. So might having that discussion force some out of the closet that aren't ready? Or, might it get some labeled as gay that aren't and cause them to question themselves? I don't agree with not teaching sex ed, as you indicated your district has decided to do, but with that being the case, isn't discussing sexual orientation in the scope of harassment and bullying stepping over that line?
I'm not saying the admin is right. Just wondering if that might be their angle.
