Just as they are threatening Trump he should do the same. “I Just got 250k people to amass at your door step with very little effort. Threaten me or my supporters one more time and you’ll learn first hand the meaning of revolution”. If he isn’t willing to go that far then he’s not the wartime leader that’s needed right now(not at all a slight at Trump).
The Marxists would welcome that. DC is an armed camp with thousands of extra National Guard troops from Democrat states and crazy rhetoric from the Mayor indicating that the Capitol needs to be defended from Trump supporters for an indefinite period and probably additional restrictions and shutdowns on the residents. Any mass movement by lightly armed or unarmed Trump supporters would give them the excuse to use full military force to kill thousands IMO.
