If they had a strong national leader, he would tell them to pick their fights strategically and carefully instead of acting out.
It is a good thing that those of us in the country who are not brainwashed by the communists get a chance to see these idiots for what they are before the revolution begins in earnest.
As an aside, Lefties around the country, with their unrestrained acting out, are creating a vacuum of leadership. Someone, not Joe or Bernie, needs to fill that vacuum to get them (the Left) focused. Right now they are playing into the President's hands (thank God).
