As if Parker knows or cares anything about Plato. And as if her readers don't know and care even less. Plato was horrified by democracy itself. He thought the best form of government was one in which there's a dictator who's a philosopher. I'm supposed to care about what would horrify Plato?I'm sure there's a Greek word for the rhetorical device of adopting the guise of someone else to deliver an opinion of one's own. It's a classic of religionists — who seem to know what God/Jesus/Muhammad thinks of what you are doing — and mothers — who've historically resorted to the terrifying news that your father wouldn't like that.
