If people want this, then yes. That's the point. Government is now in the business of deciding what we should and should not be taught. While you apparently have no problem with this as long as it agrees with your own beliefs, if government decides in the future that hollow earth theory should be taught and heliocentric theory should not be taught, then it would be within its rights to do so. Don't like it? Tough. You'll still be required to pay for it and your children (if you have any) would still be required to learn it, assuming you couldn't afford a private school.

No. If it's scientifically *valid* then yes.
