I don't really care about these arcane disputes amongst the far left. It is amusing, of course to realise that they hate each other even more than they hate us, and that progressivism is a zero sum game, but the actual points at issue are of no interest. Both groups are a bunch of total loony tunes, as far as I am concerned.
But why does it have to involve security guards and the threat of violence? Can any of you lefties explain this to me?
