The tragedy, to me, is that the socialist left has no history not because no one is willing to teach but because leftist social culture makes the young and inexperienced believe that it’s shameful to need to be taught.

Welcome to the gynocentric social order where you have to "just get it". I suspect this is also a lot of what is behind people wanting to go "post-libertarian", as our side has not been immune to this tidal wave of doctrinaire morons.
