@Terftastic, yes, I'm pretty sure.
I don't think that promoting hormone blockers to young children is appropriate, but I am reminded of nothing more than the whole debate around Section 28, and how allowing anyone into a school to talk about homosexuality was akin to promoting it.
Kids are literate these days. Your average 12 year old kid who thinks they are transgender will google to see what they can do to be more female/ male/ whatever. Better to have that talk in a school environment where teachers have a responsibility to safeguard their pupils and ensure any discussions do not promote partisan views.
