So one step in the right direction I believe is to retake the battle field. They have got Hegel? Then take him back. Show how he was opposite to everything the left is about.
And after all is said and done even the real intellectuals of the Left were aware they had to repudiate Hegel. Just for an example with Hegel morals are real and objective and can be perceived by reason, though not directly. Hegel is a plain rebuke to Hume who limits reason to perceiving contradictions.
