Its a fair point. I think many people think in booleans and if they just change one thing all will be different. As a parent you have massive influence but you are correct. Some things, many things are out of your control. In the end you have influence but not control.

I was not homeschooled but I'm a free thinker. One can easily homeschool a kid and give them the same endocrination they get in government schools. One can also send your kids to public school and augment their education. Counter the propaganda.

I think what you do matters. Kids are not blank slates but they aren't beyond influencing. Also, not all public schools are the same. And not all homeschooled families are the sane either.

I know many well socialized homeschooled kids. I know kids that aren't and went to public school. The key to me is being involved and purposefully acting. I'm no fan of the government schools but my sons were home schooled and attended a public charter school.

The worst thing parents could do would be to just make a decision based on political opinion and culture. I know some amazing government school teachers but I am aware of more that are not. Whatever people do they should be involved. Not passive.
