Two strong cultures can not exist in one space.
America was a “melting pot” because there was on strong culture and those migrating into our nation assimilated into that culture (while being allowed to keep some of their own).
That is not the case today. With hundreds of thousands from third world nations entering our nation with no intention of assimilating, friction will develop that will eventually lead to violence. Would that lead to CWII not necessarily. What we will see is that these migrants will take over territory and would be willing to kill anyone that comes into their territory, creating a “new nation” as it were.
They will be aided in this by our own politicians who will encourage and finance these enclaves.
The results I for see is more like the French Revolution then a Civil War. Citizens will turn against the government.
But we will have millions to fight, not just the aristicrats.
But I agree with you.
