No one is suggesting that the "holocaust didn't exist" should become part of the curriculum. But you'll find that such won't be the case anyway. You act as if you can't trust people to make their own determination about what to teach their kids. Ultimately you can't stop them anyway if that was truly their objective. In reality, all you wind up with thanks to that unfounded paranoia, is a system that works for nobody.

<br>As far "unless someone proves it better", our homeschooled kids score on average twice as well on standardized tests. Private religion schooled kids score likewise far higher on standardized tests. Both of those have, without a doubt, proven by any objectional standard, to be superior in every single way to our public school system. So if that's really what you want, to be proven wrong, then there you have it.

<br>In the case of homeschooled kids the statistics I saw said that 90% are devoutly Christian, on average they make less than the median household income and they are less likely to have a college education. Yet somehow, miraculously, their kids beat the snot out of public schooled kids in any and every measurable way. So your bar has already been met and exceeded by those that you claim are "backwards" and "ignorant". In short, you're wrong.
