Classic argument that if it's not their No. 1 stated goal, that means it's not among their goals.
Look at your list of achievements there: 4 percent specifically state radical redistribution of wealth (as if that's what people would call the idea of making rich people pay their "fair share".) Out of those answers, 60 percent come from hard-left ideology or are geared toward Democratic party goals. Then you have 9 percent that say "promote a national conversation" - what a typical mush-head answer, completely meaningless and IMO dishonest. No one engages in a prolonged protest like this just to "have a conversation" - I haven't heard a single protester talk about "having a conversation". You protest to affect change.
11 percent want to break the two-party duopoly, but I could easily have grouped that in the 60 percent - anyone believe there are any conservatives or moderates out there in those protesters looking for a middle party?
Then you've got 8 percent that "aren't sure", so we'll take them at their word and throw them out. So you have 12 percent that want a direct democracy or a flat tax. And that's just their primary stated goal.
I guarantee you that the 80 percent would have no problem with agreeing with at least "moderate" distribution of wealth, and likely most would call for "radical" as well. They just didn't put it as their top goal.
