Then prove it by giving some examples.

This is a pointless request, Turnoi, as I could list a dozen very good private schools in Europe that I either have personal experience of or know teachers at them and you would still not accept it as you have previously (and joyfully) admitted your bias when it comes to this subject.

You believe (blindly) that there are no good private schools, and any time this is disputed you respond with childish insults or strawman arguments. Or just say you don't believe it.

You choose to remain willfully ignorant on the subject so there is little point in discussing it with you.
