Anons, I strongly recommend reading up on '70s Leftist violence. It's incredible how much of this was memory holed. Bombings and violence against police were a regular occurrence. Did you know that a Leftist terrorist group once did a mass shooting on Congress in the House of Representatives chamber? And that Institutions like the Episcopal Church (!) helped fund some these terrorists?
It's all been completely memory-holed. It's not in the history textbooks, the pop culture, etc. It's like it never happened.
Here's an excellent read about Leftist terrorism in America. It's a long read, but I highly recommend it. I fear that this is what the present-day Left and media are agitating toward.
