Which, of course, makes him a gormless simpering fascist and a total moron.
Sure, in retrospect most people who end up doing something violent or otherwise alarming end up having made some choice remarks at some point before doing so. However, that's only significant because you've deliberately selected a population of scary violent subjects. Guess what, dumbass? You'll see a lot of very creative and endlessly vitriolic chatter from people too lazy to do much more than press the buttons on the remote control extra angrily or maybe get sloshed and throw a few punches at their similarly idiotic friends.
Until you look at the situation in terms of 'how many alarming-sounding comments actually end badly?' rather than 'how many situations that end badly have something that sounds alarming now that we know what happened?' you've got absolutely nothing.
