"But they need a diploma."
No they don't, especially if it comes at the price of rotting your child's mind and filling it with marxist bullshit.
They don't need school. All they need is 6 hours a day to become talented enough at one thing so that they can take that one thing and do it for a living. Me for example, I play poker. You don't need a diploma to go to a cardroom. You don't need a degree to step foot in a casino. All you need is talent and the time necessary to become talented.
Teach your boy how to swing a baseball bat. Teach your girl how to dance or play guitar. Do something better for your kids then send them off to indoctrination camps, run by short haired feminists who don't know anything outside their tranny approved, wicked commie infested faggot loving curriculums.
there has to be a way of organising the community and start off a group of private schools that administer a proper curriculum. like I'm sure you definitely are not the only one having a problem with the public school system and the rubbish they teach there. there must be thousands of parents like that! How do the amish send their kids to school?
The biggest hurdle is all the funding going to public schools. This would happen very quickly if funding was dedicated to students instead of schools and schools had to earn their dollars. 90% would basically become conservative overnight.
