I appreciate the talk about the importance of political violence; it is so so hard to shake the mainstream left reliance on nonviolent mass "protest" (only effective in very specific conditions which largely no longer exist in the US) vs acts of actual resistance like collective action at work or direct action against uniquely vulnerable targets.
If protests were not effective, then they would have fizzled out already
But this is not true. I think that despite explicitly rejecting this line of thought you've accidentally gotten caught. I think that American-style street protests do nothing, and so the ruling class only lightly represses them in order to provide a safe outlet for discontent and ultimate demoralization. For instance, did the massive protests against the Iraq war actually work? What has one year of protests against Israel's genocide of Palestine actually accomplished? We are too quick to reach for protests when we have better weapons.
