People are (and have been) taking to the streets. Americans tend to think that a protest must involve everyone otherwise it’s pointless. They don’t realize that protests typically involve a tiny fraction of the population. The more, the better of course, but stop sitting around waiting for it to get big. Either get out there now or find other ways to contribute. There’s plenty to be done.
There was a study a while ago, analyzing previous events to estimate which percentage of a population needs to become active to effect meaningful change. The number was surprisingly low, I think less than 5%.
It's about 3%, and the study had major flaws in its context; large westernized countries are out of scope. I don't remember paper, but I just lost this argument to a lawyer.
