This is not new. Only 1/3 of the Patriots backed the Revolution. One-third fought with The Brits (civil war).
In 1812, the only thing that kept us from secession by the Northeastern states was AJ’s victory in New Orleans and the peace treaty. (another civil war).
You could say we had a civil war in the 60s.
In one of my college history classes, the professor said only ten percent of the colonists backed the Revolution. Eighty percent had a don't-care attitude and sat back. A minority of colonists did the actual fighting against the Brits. Another reason why we need to keep Muslims from infiltrating our nation, as it only takes ten percent to foment a rebellion while eighty percent sit on their butts doing very little.
