"the worst in our society" appeared during the Summer of 2020!
They wore black uniforms (reminiscent of Nazi SS) instead of 'brown shirts', and showed up for their "peaceful protests" wearing body armor/padding, helmets, face-shields, and stout clubs holding their "signs". They then engaged in illegal trespass and occupation, riots, looting, mayhem, arson, assaults and murders, illegal firearms possession, attacks on police and government buildings, insurrection, and sedition. Just for a start on the list of the their "lawful" and "peaceful" crimes against our nation, our government (you do know what "autonomous zone" means?), our Constitution and their fellow citizens. This wasn't for just a few hours, or a day or two, but for many months and across our nation.
One can't get much worse than the parasitic, useless, deadwood, anarchistic shyte that composes the "storm troops" of the insurrectionist Left; which is the fascist arm of the Democratic Party. There was nothing "anti-fascist"(AntiFa ?, what a laugh) in their months of insurrection in scores of our cities by tens of thousands seeking to destroy our nation from within.
There's your "cult-like behavior"; and the infectious disease has not been eradicated!
