While I find the Republican right dangerous and anti democratic, I have to agree with the guy that the far, super purist left can sometimes be a little more than just annoying. In fact it was those of the far left who refused to vote for the lesser of two evils who brought us the ultimate evil in Trump.
PS I was a Bernie supporter but refused to waste my vote in a way that let the devil enter the White House. Often it is not the right that brings us Republican presidents it is the self-righteous left refusing to be pragmatic.
