To them, anything that isn’t far-left is “far-right”.
So anybody that starts at their “center”, which objectively is far-left, and gets exposed to arguments that moderate them in any degree, is getting “right-wing radicalized” even if they are still way left of center.
The problem is the left claimed the center to move the argument and it was not properly contested.
They do not believe that a FAR left exists.
There is no system so far left that it is considered extremist or horrific.
Bernie Bros are defending Stalin’s gulags now.
Bill Ayers was for killing 25 million who couldn’t be politically re-educated.
Connected Democrat Jim Jones killed him flock and had agents of his cult hunt down those who escaped or talked after the mass suicide.
They quoted Mao, they celebrate Che and Fidel. They carried the North Vietnamese flag at supposed “Anti-war” protests. They recently marched in major US cities promoting Communism, cheering the Iranian government while denouncing the US government. Not one march after the Iranians shot down a passenger jet killing all on board.
ISIS and such would be considered far right. They might not have meant to but on that they are absolutely correct.
