The American Left is becoming more like ISIS every day, in terms of promoting their beliefs by violence, shutting down any thought, idea, or speech, that they happen to disagree with, and blowing up monuments from antiquity to erase any form of history that they do not wish to recognize.
If the current trend continues, it will end with Leftists blowing up Mount Rushmore and outlawing the display of the American Flag anywhere in any form.
BTW, this is not intended to be hyperbole. This really truly is the direction they are heading.
