Look at the right wing movements in history. Fascism, Nazism or any other right wing movements. These largely arise because there is too much politically correct talk going on, and at some point a guy comes along and musters the courage to say all the things openly what others had been wanting to say for years. What he says could be totally wrong and may be even absurd. But the fact that people just need a vent to release years worth of accumulated pressure will buy a lot of public validity.
Once this happens the public support, mood and direction swings too much to the other end. At this point PC won't even matter.
He's saying "Isn't it kind of strange that everyone else seems to have completely lost their minds?"
There was quite a bit of PC. Germany was paying huge war reparations to France and UK. It was sort of portrayed as 'atonement of sins'. Economy was in tatters. There was insane levels of humiliation dumped on German populace for losing WW1. People were expected to simply eat it up as moral punishment.
None of this justifies WW2 or Nazism of course.
We're experiencing a polarization and lack of an ability to abide other's beliefs.
Now that firing someone for their beliefs has been demonstrated, how surprised will we be when bosses fire more people for their beliefs?
As aware humans, we should all be able to be better than this.
Events like firing people for holding a belief, only reinforces their belief further that they are being marginalized for merely holding an idea in their head. Of course they will now keep quiet until somebody comes along and generates way more groundswell support for their belief.
This isn't just in America. This is happening all over the world.
Right wing politics is now the only refuge for people who want to speak their mind.
As much as scary this is, this is the truth.
