Some thoughts....
1. "He who controls the purse controls everything." Public schools are funded 100% by politicians. It is therefore simply the reality that they will control what is done with that money - regardless of them knowing NOTHING about education.
2. Politicians are... well.... politicians. They are experts on the art of POWER. They seek to control society and they seek to control voters in such a way as to get re-elected. It's just what they do. This is easiest with the young as they formulate their political, moral and social ideas and philosophies. When they graduate from high school, they become voters. Their social, moral and political ideas - which hopefully they formed in large part from their education - will now be put into practice. When Alexander the Great expanded into new lands, his goal was to make them GREEKS in EVERYTHING (right down to dress and architecture). He skipped right over adults (too hard to change them) and focused on children..... he was the first in history to form public, state-funded, required education... to make them GREEKS. He knew in 20 years, he would succeed in making his empire a GREEK empire.
3. I live in the People's Republic of California, a wonderful state I deeply love, but it is a ONE -PARTY state and that party is extremely liberal (and with no counter-balance, gets more and more leftest every year). As a result, history books here are anti-American and stress how great are native Americans, illegal immigrants, LGBT etc.... "Health" education is mostly about how masturbation is a sacrament, how kids are probably gay and need encouragement to "come out" and how sex is just natural and as long as you cover things, it's wonderful. Since a lot of teachers are liberal democrats, they have allies. Now, SOME teachers (my wife was until this year) do their best to "lay aside" all the liberal JUNK (on the day they were to celebrate the Gay Pride flag, she and some other teachers taught and celebrated the AMERICAN flag - the principal just pretending he didn't notice).... she simply skipped nearly half of the "health" lessons and never taught them. The SAD THING IS.... parents don't care. Including Christian parents. They can "opt out" their kids from this junk but none do; they can come and view all the sex ed stuff for themselves but none do. No one protests this liberal brainwashing. And so it just gets worse and worse... and because time is taken away from reading and math to teach the glories of same-sex marriage, reading and math scores suffers - and teachers get blamed for that.
My son is going to go to a private, Christian school.
