Anger

While at times a healthy emotion, on it's own it has never really clinched anything.
Attention: many, many people who could be fed up with whatever it might be.
Look within. Collectively this is where the true harmony and repeatable positivity will lie.
Anger + Equanimity may seem like an odd equation, but it is the source of the solution.
See MLK, Ghandi, for two examples.
This is the place we will need again go, making history in coincidence with history.
