However, I'm highly doubtful that most of the people in attendance have read into the organization's aims.
Very true!
At the same time, I find it hard to believe that something like BLM is any more "organized" than Anonymous is. They both seem to be flags waved by folks who want their event/movement to seem larger/more grand than it is if it's just them.
This is something really interesting to consider, kind of eye-opening.
