I actually agree that sex ed on schools shouldn't be mandatory - Maybe it's because of the culture I've raised in, or it's just my defense of the rights of parents which, in my country, have progressively diminished in the name of "safety" and "health". I do agree with a comprehensive programs from those who wish to have those classes, and I think homosexuality should be included as it is a sexual orientation and not everyone is straight. I don't think teachers should be saying what their opinion this, or if they're tolerant or not, or if they're gay or straight personally, only facts should be exposed. I hate the idea of the government programing its education according to an ideological agenda, even if it's an agenda I particularly agree with.
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
