I think this is going to be very controversial on the typical HN crowd: maybe too European, or too socialist. However here it goes. Some ten years ago I was convinced that private schools had a right to exist, but that they should never impact the funding of public schools, not even indirectly. Then I discovered that homeschooling was a thing in the US. Now I tend to believe that private schools should not be allowed…
I recognize that there are some in the homeschool "community" who are ruining their children (imho). For the sake of freedom, I accept that there are terrible people in the world who should not have reproduced, but for me to have rights they must have them too.
