> What's "actual" education? One's personal opinion can differ.
A good education is one that reflects reality. If your opinion of what reality is differs from mine, you're welcome to show me wrong using experiments. Otherwise, you are wrong and are not likely to be a good educator.
> The debate about mentioning creationism in schools shows that both sides see the school as the indoctrination vehicle
Not to the extent you seem to think: One side has facts on its side, whereas the other does not. If you can't see any asymmetry there I refuse to try to help you.
> Of course, you or I may not like their choice, but why should they care?
Because I have to live with the laws they have the political clout to force through Congress. I have to deal with the fact they have just as much political clout as I do and no idea why the tides come in or why trickle-down economics is a terrible idea or why banning abortions doesn't magically make everyone into someone who can raise a child in a reasonable fashion.
