Not all protests for Gaza were meant to gain engagement, many were organized to cause direct economic disruption to those that profit from the war, that is a goal.
I actually totally agree with you. I should've been more careful in the text to distinguish between those two very different kinds of actions. I actually really, really like things that disrupt those that profit, but those are not nearly as common as going to the local park or whatever. I might throw in a footnote to clarify.
