The biggest problem with the Berkeley antifa protesting is the lack of unity / direction. They aren't gaining any traction because their message is just a general disdain for the current state of the government. It's less direct action and moreso rioting. Antifa and other leftist protests traditionally consists of focused direct action. This can still lead to violence from skinheads fighting back against Antifas crashing their Klan meetings or something, but who cares.
