An ‘ally’ who goes along to get along, but has a radically different value set is not an ally. “9 people sit a a table with a Nazi and say nothing - how many Nazis are at the table?” We decry the Russians who don’t speak out against Putin, but shuffle uncomfortably when the DNC’s top candidate is pursuing a path that enables atrocities?
