Unfortunately, yours is the standard, bigoted view of both the South and the Confederacy. Let's not forget it was the North that invaded the South making the North the enemy.
Yes, there are a few dipshit bigoted cocksuckers who are racists and use a noble battle flag for very low class purposes, but they are a minority. People like Bobb and CFM (possibly the same person) are rare. Not all of those in Michigan were racists just because they were flying a CSA flag. Most believe in States Rights over Federal Authority; something Trump declared he had then backpedaled from it.
In Michigan, they were a bit misguided because it was their own governor ordering the lockdown. Despite all of Trump's blathering about how he's king, the final authority, tin-plated dictator, whatever, he doesn't have the authority to shut down a state. It's all on the Governor.
