The hubris it takes to continue not knowing that one doesn't know! What has he done all these years? Does he read? Hasn't he read or heard about the many books written by former Communist block dissidents where they speak of the damage that had been done to their cause by Western useful idiots and fellow travelers such as himself?
But then, this is the same question I ask about the bookstore employees who display books by those former dissidents and even host their author readings but stubbornly remain hard core Communists (although they call themselves "Progressives", of course) throughout. It boggles the mind, doesn't it?! I can't explain it...
