A service ramp at the rear of the basement led to a sliding door that opened into an alley; the police found the door had been tampered with so it could be opened without unlocking it. The block is then released from rest. In these enactments, they attempted to think with the playful dogmatism of a feminist tradition that they call "crotchless pants and a machine gun" (obviously referencing Valie Export) in order to locate what might still be useful today about the somewhat beleaguered "second wave" feminist . <> 4) the dominant group (mainly white men).
