My take on this is simple: It is better for a good book not to be taught at all than be taught by the people quoted in that article. Yes! — do, please, refuse to teach Shakespeare, Homer, Hawthorne, whoever. Wag your admonitory finger at them. Let them be cast aside, let them be scorned and mocked. Let them be samizdat. Let them be forbidden fruit.
They will find their readers. They always have — long, long before anyone thought to teach them in schools — and they always will.
