I think if the Yanks try too use force we'll have another civil war. (No legal mumbo jumble =force. The only force that can accomplish that is military force).The North won the last time & they probably would win again, but they suffered a lot more casualties than the South, are you sure you want to do that again over a flag?
I think you are losing the culture war, so it won't come to guns.
