Why is there such a crappy view on homeschooling ?

Because liberals in particular use public schools to indoctrinate. Without access to your child they cannot work on their fears.

People who think for themselves are always viewed as a threat to globalists.

In the liberal playbook, they freeze unwanted behavior. Then denigrate and ridicule it. This is the most common attack.

Don't be swayed. You are doing the right thing by taking your child away from them.
