Total bullshit.
Firstly, be careful not to be grossly misinformed about the kind of people who generally homeschool their kids. By and large they aren't crazy nutjobs out of touch with reality, or people who can't control their delinquent kids, most of them are normal parents scared to death of sending their kids into the state-sponsored slaughterhouses that pass for schools in this fucking pit. And yeah, obviously there are situations where you have lousy parents who screw up their kids by providing poor education, but it's pretty rare that those cases actually matter. If the parents are really that lousy, chances are their kids aren't even trying to learn anything in school anyway, so who cares where they spend their time not learning? Simply sending your kid to a state school doesn't provide *any* assurances that they'll turn out decent or learn anything, and the conditions are so laughably bad here in a lot of cases that if you aren't an idiot, chances are very good that you'll give your kid everything they need without the extreme risk of sending them to one of these pathetic public schools.
There are plenty of kids who come out of public schools fine, but take a look at the youth of the bay area. Come out here, spend some time in the city, get to know these people, and you'll realize that there's something incredibly wrong with the system. It just doesn't work reliably, and we've got some of the most worthless children you'll ever meet in your life out here. And it isn't like it's just a few, this is en masse, and it's a fundamental problem that affects a whole lot of other things.
Anyway, I obviously have strong feelings on this issue. But this is total crap and I'm obscenely angry right now. Make no mistake, this has absolutely nothing to do with education. It has everything to do with those in power who will go to any lengths to squelch personal belief and force their people to accept their own dogma, be it scholastic or otherwise.
