The Weather Underground, founded by Bill Ayers and Bernadine Dohrn, was a radical left militant organization active in the late 1960s and 1970s, founded on the Ann Arbor campus of the University of Michigan. In the 1970s, the WUO conducted a bombing campaign targeting government buildings and several banks. You may know Bill Ayers as the guy who got Obama started in politics...

Weather maintained that their stance was "an anti-imperialist, anti-racist struggle" and warned that other political theories were "bound to lead in a racist and chauvinist direction" and needed to be "smashed".

Members of Weather further contended that efforts at "organizing whites against their own perceived oppression" were "attempts by whites to carve out even more privilege than they already derive from the imperialist nexus". Weather's political theory sought to make every struggle an anti-imperialist, anti-racist struggle; out of this premise came their interrogation of critical concepts that would later be known as "white privilege".

At one point, the Weathermen adopted the belief that all white babies were "tainted with the original sin of "skin privilege", declaring "all white babies are pigs" with one Weatherwoman telling feminist poet Robin Morgan "You have no right to that pig male baby" after she saw Morgan breastfeeding her son and told Morgan to put the baby in the garbage. Charles Manson was an obsession with the group and Bernadine Dorn claimed he truly understood the iniquity of white America, with the Manson family being praised for the murder of Sharon Tate; Dorn's cell subsequently made its salute a four-fingered gesture that represented the "fork" used to stab Tate.
