“I see the blue states getting bluer and the red states getting redder”
The facts bear this out. Eventually this country will split up. The two sides are not compatible with each other.
Will it be peaceful like the Czechs and Slovaks, or unpeaceful like India and Pakistan?
Likely it will not be peaceful. There is one side who predominately want to be left alone (the red side) and the other side who believes they are right and evil must be defeated (the blue side).
It is a cultural jihad by one very self-righteous side though they are blind to their own self-righteousness.
