I hear this all the time and it is just propaganda
There is not a great divide.
The hatred is coming from extreme people on the left in coastal cities.
Normal Americans wether they are republican/Democrat/libertarian or anything else believe in America.

Yes they may differ on how big government should be and what role it plays but they believe in America. That means believing in the constitution. Believing in the right of free speech (he’s that means ALL speech is free.

The far left coastal liberals have always been there. They are a super vocal minority. They have the internet now and represent a much larger share of online writing than regular Americans. so it appears ther is a great divide. That is there goal.

If you truly believe there is a divide I would say unplug, move off the coast and see how regular Americans work & play and don’t even talk about these things.
You would then see how extreme these people are.
