I'm still trying to bend my head around that quote.
The writer says that for a lesbian to not be sexually attracted to a TW is transphobic.
Ok. Unpack that a little.
It may be a fully intact male body, with male shape, male musculature, male size and proportion, but the writer identifies as a woman inside so a lesbian MUST recognise that women's bodies are varied and include male type bodies. If you are lesbian, it's woman to woman and that means all women, you can't just pick the um, born women ones because that's who you realised you were gay by being physically attracted to from an early age. Very naughty of you!
Ok. I don't agree but I can just about follow that logic. The writer equates it to not being attracted to fat/unfit bodies, so sees it as a hesitation over a mere cosmetic difference. And it's driven, also understandably, as so much of this is, by deep hurt at defining as a woman but finding others have boundaries that mean they don't unquestioningly validate and participate in that personal redefinition.
Where I get completely lost is that the writer is stating that lesbians must all
a) buy in without hesitation or question to removing all separation from male/female bodies: the person is what they say they are. The evidence of your eyes is irrelevant and so is your natural sense of physical attraction. Both must be ignored/re educated.
b) Lesbians may not place any boundaries around what they are attracted to: that is very naughty. If told a body is female they should be open and willing to have sex with it. Hang ups about not liking penises, different musculature and all the rest of it are silly hang ups that mustn't be tolerated. It's a woman's penis, you're a lesbian, abandon everything you ever knew and get on with it.
c) How does the writer propose that I overcome the fact that shamefully, appallingly, male shaped bodies just don't attract me?
I would like the writer's views on how to force someone to learn to become sexually attracted to something? Re education courses with specialised pornography that you must use until you are successful? Fake it until you make it and realise what you were missing? Brainwashing perhaps? After all, no one's ever tried using straight sex, intimidation, corporal punishment or brainwashing gay people before after all to try and force their orientation to something more socially acceptable - hang on a minute. Yes they have. For centuries. It didn't work. And it's been known for decades as being severely abusive and homophobic.
This is the definition of FUBAR. Seriously.
