Perhaps you misunderstand... I mean each child's education should be completely controlled by the individual's parents, and not the parents of other children. I don't care how many parents want my child taught that 7 year old sex is moral or that phlogiston is the product of combustion, If I don't want them taught that then that's the way it should be. School choice is the answer.
First of all, wow! Kudos for successfully working the word phlogiston into a conversation. That opportunity doesn't come along that often! haha!
Secondly, in theory, I can agree with you. But in practicality, I don't think you can truly say "If I don't want them taught that then that's the way it should be."
Schools don't work on a one-on-one basis. Teachers typically have around 30 kids per class. That's 60 parents, all with differing opinions. There is no way that they can successfully please all parents at all times and still educate the kids.
Now, in this circumstance, perhaps they should not be teaching acceptance of homosexuality. I can agree with that. However, I don't like the blanket statement of "If I don't want them taught that then that's the way it should be."
