How many degrees of separation from Trump do you think people should go? "It goes without saying that if the people of Group X are staring at you demandingly, waiting for you to hate the right enemies with the right intensity, and ready to castigate you if you fail to castigate loudly enough, you may be hanging around the wrong group." - http://lesswrong.com/lw/42/tolerate_tolerance/
