Beth Elliott is a transfem folk singer who was involved with West Coast lesbian political movements in the 70s. her inclusion was debated for a while, partly because she was transgender, but also because a lesbian who she used to have a relationship with was involved with a separate lesbian group, who protested against her inclusion at a lesbian conference that she had helped to set up. the conference took a vote that resulted in the majority saying she should be allowed to stay, but the trans-exclusive lesbians refused to allow the vote to hold. she performed once on the first night, and then didn't return, and the next night one of the speakers delivered a speech that was changed from her original notes to be more of a transphobic screed against Elliot, alleging her of having "the mentality of a rapist". this incident certainly didn't *invent* the idea of trans women being rapists, but it does predate The Transsexual Empire by several years and was definitely a contributing factor to its creation.
and i say "is" at the top of this story because Beth Elliott is still alive!!!! this incident was not that long ago!!!!! it DID damage her career, however, and it practically made her a social pariah. but it's the same type of shit people do to trans women to this very day. these tactics are relatively recent overall but they are still time honored traditions with trans-exclusive feminists.
