Emotionally satisfying, politically useless

I saw this quote (of Barney Frank‘s) at Harry’s Place and just had to repost it:

“I believe very strongly that people on the left are too prone to do things that are emotionally satisfying and not politically useful. I have a rule, and it’s true of Occupy, it’s true of the gay-rights movement: If you care deeply about a cause, and you are engaged in an activity on behalf of that cause that is great fun and makes you feel good and warm and enthusiastic, you’re probably not helping, because you’re out there with your friends, and political work is much tougher and harder.”

Harry’s Place quotes this as the source.
