The problem with all of the extremist views (from both the liberal and conservative side) is that while it seems like there was a massive rift between two sides, it was just a loud small group of morons yelling at each other. And worst of all, when everyone calls everyone a racist/sexist/etc, when someone that REALLY is those things comes along... the meaning is now lost. Sort of a boy who cried wolf scenario.
Now here we are with Trump.
