While I agree with many of your arguments, we are not talking about removing John A from currency or history books. Keep statues if you must,  but his name has no place on a school. John A Macdonald and his policies of assimilation and cultural genocide were carried out in schools. For Indigenous people experiencing historical trauma as a result of this system of "education," having John A's name on schools serves as a painful reminder of abuse and loss. Today's schools are supposed to be safe and inclusive environments and as such should not bear the name of those responsible for their suffering.
