I am old enough now that I have seen the outcomes projecting into peoples 30s. I know so many poorly educated homeschoolers whose lives have been destroyed with no hope of recovery by the complete lack of skills their hyper religious parents imparted them with, in jail, broke, unable to hack it in college and too lacking in common sense to make it in the trades or professional work, with living standards insanely far below their parents. That being said, I am not against homeschooling personally and may do it myself.
I think your outsider perspective makes sense since you didn't see the self-righteousness and persecution complex inherent in the system. It's like a northerner taking "bless your heart" at face value because they're dealing with a degree of cowardice and dishonest duplicity they haven't experienced before. All the best people I have known have been atheists or "religious" people who don't take it seriously and just follow their own inherent internal moral guidance (which is all the religious people are doing as well, as at core everyone acts as they choose to act.)
