If you mean that literature, history, philosophy, etc. are currently being taught badly by many politically-indoctrinated fools, that's one thing. But if you mean that the subjects themselves are useless and should be closed down, I would consider that one of the most outrageously uneducated -- and useless -- remarks I've heard in my lifetime.
I'm not denying that there is great benefit in studying them throughout ones life. Perhaps if the subjects were banned they would be better studied.
