Why are you selected only one aspect of his character to argue against?, in isolation it would be unreasonable - but when it's combined with other factors related to extreme privilege (both educational & economic) it does create a picture.
whose character? i didn't argue for or against anyone's character merely against the stupid notion of using a persons school as a stick to beat them with.
but if given the choice between sending your child to a top school and an average one which would you chose?
and later in life would you be annoyed if someone judged them or criticized them on which school they went to?
it's a very silly argument that when turned on thier own children gets the same people annoyed "how dare you imply my son is stupid because he dint go to a good school" etc, but they're happy to judge someone else child by the school they went to.
