On a spring 1970 news master, there is a short story about the Society of Female Terrorists (SoFT or SOFT). It seems to be a short lived group of which Katherine Smith was a member. They coincidentally came onto the scene just as the controversy over Abbie Hoffman’s visit occurred. Their name sounds much more controversial than their aims, which Brown explains in the audio.
Below is the one Thresher article that mentions the group.
