Nothing, because he is a useful idiot. He just refuse to accept that no all people are the same, that the blank slate is a lie, that genes determine in large part a person ability, that it determines culture, and that culture determines politics, and that elections have consequences.
He really does think that some how we can "get rid of welfare" (never explains how, it will "just happen"....somehow) and this will some how bring about a utopia, that some how people will rise above their biology, that water will turn to wine, and the lion will infact lay down with the lamb...
That if in fact he is outnumbered, he will just repeat the same augments enough and that some how the invaders will "see the light", that they will some how "just get it", never mind all the data that proves this to be the case...
To him, if America dies its not because we refused to defend it or people like him stabbing it n the back, it is "our fault" for not "doing a better job" at "spreading our message", never mind that some messages are not meant for other people, cultures, etc...But hey "at least GDP increased by 0.005% this quarter".
