Offered for discussion. I'll put my personal reactions in the comments.

"Given the left’s vision of itself as the tribune of the people, it’s a bitter irony that conservatives have proved so much better at grassroots advocacy. They are likelier to forcefully inform members of Congress of their policy preferences; liberals are more inclined to hold public demonstrations, in which like-minded people gather to reassure each other of their beliefs. Writing or calling your representatives and senators, and organizing others to do so as well, is not inherently exciting and relies on the implicit belief that representative government works as it should. Applauding speakers who denounce the unfairness of a particular situation and rail against the political system is more emotionally satisfying— but very much less effective. After years of pleading with allies to favor the first course over the second, I formulated a rule: If you care deeply about an issue, and are engaged in group activity on its behalf that is fun and inspiring and heightens your sense of solidarity with others, you are almost certainly not doing your cause any good."
