One of the reasons I drifted so far left was because of a constant sense of outrage. It was like a steady drumbeat in my head: Capitalism? Patently unfair! Unequal pay for women? Outrageous!
Of course, out here in Berkeley, I was in good company, surrounded by the multitudes up in arms most hours of the day. There's even a popular bumper sticker around town that captures the general vibe: If You're Not Outraged, You're Not Paying Attention.
