American politics has always been divided and polarized. But this is only the third time that it has become seriously debilitating. There was the Civil War, then Vietnam and the Sixties and now Donald Trump. The previous two were won by the good side and changed the very nature of American politics and culture forward forever. This one is more of a flash in the pan rather than any great sea change. And they always lose in the end anyway. The only issue is how many people they take down with them.
Now it is the same hardcore OTHER SIDE which has always been about 30% of us, but this time they were empowered by a PT Barnum cult leader who was able to whip them up with fear, with hate, with bigotry, with ignorance and resentment to get out their vote as never before. It is how all dictators, fascists and despots have gained power. Most always blaming those of other colors, religions, ethnicity and funny names for all their woes. Which always ends very poorly.
Their ship is sinking after only a few months of their silly crap. So relax and resist.
