But, from my point of view, the most disturbing and troublesome attacks are coming not from outside U.S. borders, rather, they are originating from dedicated leftists (i.e. socialists and communists or sympathizers, and anarchists) and immature students who simply do not realize what an easy and beneficial existence they have, especially when compared to the generations of their parents and their grandparents.
No individual, no government or system of government can ever be perfect, and when systemic failures are found, change and reform are accomplished by dedication and hard, honest work, not by shouting down those who disagree or by looting or by burning. Those who shout down and loot and burn are the cowards among us, the weakest among us, the most selfish among us, the destroyers among us, the haters among us, the delusional among us.
So, look in the mirror .... who are you, which are you, what are you ??
