I'd suggest home schooling or private schools if you're that worried about it honestly. Personally, I have a love for education, all of it, so I do not mind my kid's being exposed to a "fuller" spectrum (of all subjects, not just sex ed.)
I'll admit that discussing sex with my kids has been a bit... uncomfortable for me because I'm a bit of a nympho but I don't want /them/ doing it - hypocritical lol... Basically the gist of my convo's with them is "hey sex is great, but you don't want kids or some STD so don't get stupid cause I'm not paying for your kid and your entire life will be screwed." It seemed to work alright.
So you are for promoting sex with the lower digestive tract in reckless adolescents notorious for not using condoms eh? Boiled down, you are for promoting death of children and young adults. OK, got it..
So you are promoting anal sex for kids.
You are for promoting the death of children- and homosexuals of course.
