I don't believe the far-left does. I believe a subgroup have fallen for far-right propaganda that was disguised as leftist. I'd consider myself pretty far left, but I recognize that the messaging coming out of certain groups is not their own. They are just gullible enough to fall for it.
They both work for the billionaire class and benefit from the 2 party system. The status quo suits them just nicely. That's what the far left says and I don't see how they're wrong.
