I'll add my voice in agreement with Gary Farber's here.

Barbara O'Brien makes the case in her post that the civil rights marches of the '50's and '60's should be the models for current public protests.

Serious clothes, serious language, single-pointedness and respect for the audience are among her recommendations.

You'll note that laying one's nekkid fat hiney in a field in formation spelling "MAKE LOVE, NOT WAR" is not included there.
