Reports are seeping out of NYC that these people are sort of like the "traditional" Earth Day participants - you know, people with barely a brush with personal hygiene who demonstrate their concern for the environment (and other issues) by descending on parks, the National Mall, Wall Street, etc., trashing the place, and leaving behind everything from everyday litter to human fecal matter and used condoms for SOMEONE ELSE to clean up.
The sad thing is, they do make a few good points, but for the most part they remind me of the sort that Al Capp lampooned in his comic strips a couple of decades ago as S.W.I.N.E. - Students Wildly Indignant about Nearly Everything.
