In the 1950s, the Montgomery bus boycott targeted the city buses, not the black cabbies in town. In the 1960s, anti-war protesters targeted the Johnson administration, not Eugene McCarthy. In the 1970s, second wave feminists burned their bras in protest of the Miss America pageant, they didn't protest Betty Friedan's speaking engagements. Today, Greenpeace protests Shell Oil, not the Sierra Club and Occupy Wall Street protests Wall Street, not homeless shelters. So targeting a seeming ally seems counter-intuitive to me as someone who has studied and participated in justice-seeking protests for three decades now.
