You're the only one who has shown any concern for the poor girl that is being deceived, and what it will do to her to discover she has been duped into a lesbian relationship.
In fact, a friend of one of my daughters had a similar experience. I don't think they ever kissed, but this "boy" was really putting the moves on her. Called, holding hands, talking endlessly on the phone. The girl -- a really nice girl who hadn't had a lot of attention from boys -- was just devastated when she found out the "boy" was a she, from another town. A sick, selfish, "she," who didn't care who she hurt when she dragged an innocent girl into her little perverted hell.
And clearly these teachers don't care about how people that this person has relationships might react. I suspect that they think that the suprised kids will learn an "important lesson" about "tollerence" and "gender identity" and it will help teach children their real agenda which is that they think sex isn't about long term relationships, marriage, and children but just about the desire and sex.
I thought that homosexuals "swear" that they are never attracted to heterosexuals. This is why the is nothing to be concerned about with gays in the military, etc.
