'NO teacher has the right to make my children, or anyone else's feel bad about themselves. No other human being does'

so how about.......

"The products of schooling are, as I've said, irrelevant.
Well-schooled people are irrelevant.
They can sell film and razor blades, push paper and talk on the telephones, or sit mindlessly before a flickering computer terminal but as human beings they are useless.
Useless to others and useless to themselves" ?
