Actually, the government is defining students by a "sexual orientation" when they are not, as yet, legally in possession of the right to consent to sexual activity. Thereby, they are providing the orientation toward and in fact promoting illegal activity. Isn't this a racketeering case?
Actually, I think most of these kids are 16+.
But I don't think that a school which promotes heterosexuality as the appropriate orientation for its students is guilty of promoting illegal underage practice of that orientation. And certainly the sex-ed classes in all the regular NYC public high schools are actively endorsing underage activity, so I don't think you'll get far with singling out HMHS for criticism on that point.
