A protest is a statement, not a force for change. If there is a dominant message, it can result in or block a legitimate people's movement for change.
Much of the country understood that the years of the Obama administration represented our last chance to bring the "masses" back together, forming a movement based on the common good. It was worth a try. By the time that Dem politicians and liberal media successfully redefined Occupy as a "movement of middle class workers" alone, we knew it was over.
What, exactly, are anti-Trump people protesting? The gods of US politics gave us two candidates who were deeply opposed by much of their own voting bases. Clinton ended up with the majority of the popular vote, the Electoral College picked Trump, and that's how the system works. Now what? Everything comes back to: We'd love to wage a revolution, but can't get enough time off from work. We can't risk losing our jobs because there's nothing to fall back on.
