Glenn Greenwald finds virtue in public anger:

[The] anti-anger consensus among our political elites is exactly wrong. The public rage we're finally seeing is long, long overdue, and appears to be the only force with both the ability and will to impose meaningful checks on continued kleptocratic pillaging and deep-seated corruption in virtually every branch of our establishment institutions. The worst possible thing that could happen now is for this collective rage to subside and for the public to return to its long-standing state of blissful ignorance over what the establishment is actually doing . . .

It's a universal dynamic that elites want to keep the masses in a state of silent, disengaged submission, all the better if the masses stay convinced that the elites have their best interests at heart and their welfare is therefore advanced by allowing elites -- the Experts -- to work in peace on our pressing problems, undisrupted and "undistracted" by the need to placate primitive public sentiments.

Consider that it is now well established that emotions are not incompatible with rationality.
