An interesting side bar that one gets from reading from West to East is that little has changed in 100 years amongst the far left. Anarchists were guilty of several bombings including most likely the unsolved bombing of Wall Street around the turn of the century. The history of bombings colaberation with a hostile foreign powers is what the far left has done in its entire history. The mere fact that someone is an anarchist or a Marxist is probable cause for scrutiny law enforcement.
The constant themes of class warfare and trying to undermine the war effort in WW1 are there. The antiwar speeches are strikingly similar except for some anti semitic references that are not in the WW1 speeches. The truth is that the peace movement is not about peace and never was. It has been used and coopted by Marxist and Anarchist thugs whose true aim is the destruction of capitalism. Interestingly left wing movements have historically been racist and anti illegal labor. Now the far left pull a Linda Blair and organizes the illegal worker rallies on May 1.
The left also does not discuss the medling of American leftist in Mexican, Chinese and other revolutions. Nobody elected these people to anything and unlike th US government they are violating the law. Do note that mercenaries seems only to be the name given to those who opposed Marxism. When Commie vermin pick up arms like the infamous Abraham Lincoln brigade they are fighting Nazism. I hate to break the news but fighting to impose Communism is just another brand of evil.
Our country should learn from the past and start enforcing the laws on treason and sedition. Marxist, Anarchists and Jihadis should be constantly watched by law enforcement. Routine violators of the law should be stripped of citizenship and deported. Those who commit serious acts should face the death penalty.
