I can appreciate the stance taken in that writing.
It's often bemused me on these boards the prevailing view about lesbian erasure, and the policing, the gatekeeping that goes into preservation of the terminology - I find it quite paradoxical in that these efforts are in fact more likely to lead to lesbian erasure in and of themselves...an increasingly small number of women who can fit into that category because of the gatekeeping...what if you've slept with a man in the past...what if you've had an attraction to a transwoman? You're at risk of being told you should identify as something else, not a lesbian - those women are being erased from the category.
The militant gatekeeping efforts also create a large number of women who are unwilling to identify with the descriptor, because of the negative associations they now have for it...they slip out of identifying as lesbians not because they technically aren't, but because psychologically they can not reconcile themselves with what the word now means to them. So they say they're gay women, or women who sleep with women etc etc. They erase themselves from being lesbians.
The gatekeeping, the groups like 'Get the L out' are also taking space away from young teenagers who might otherwise fit it. People who are uncertain of their gender identity and sexuality, who conflate the two, and then see the hostility and division coming from some quarters and think 'Well, but I certainly don't want to be associated with them' and are of course naturally drawn to the 'be kind' philosophy and more welcoming, open attitudes and broader spaces to inhabit whilst they find their way. More potential lesbian erasure as some, in the confusion, complexity and stress of adolescence, may come to feel that actually they are in the wrong body, rather than that their sexuality is directed towards women.
The reductionist, easy definitions promoted by some streams of feminist thinking do not encapsulate the complexity that exists, and are paradoxically in danger of actually subverting their own ends.
I can see the parallels made in that piece to other styles of thinking and control that have existed throughout history and I get that. To my mind what underlies a lot of this is a fear mindset.
