sparky about your point earlier about how trans MTF may not have had the experinece of growing up as a female in this society, but they have very likely had a difficult time of it, and a struggle, in other ways, and therefore can't we all be in the same struggle.
Well not really.
Feminism is to do with fighting sexism and male oppression, and in order to fully understand how sexist our society is, you need to be on teh receiving end. People who have only observed sexist behaviour, even if they find it appalling, will usually not be able to fully empathise with the victim. The sexism in our society starts with birth and is compounded every day after that. By the time a female leaves school she will have been bombarded with things that have happened to her because of her sex, that will have entirely shaped who she is. It is a very specific set of experiences.
So having a shared bad time of things can make people sympathetic to each other, yes, but I would say that they can't entirely understand.
That would tie in with the total lack of interest in anything which affects women in general from reproduction through FGM through girls being forced into prostitution and the whole range of things that are happening to women around the world, in the trans feminist manifesto. you might argue that I have not personally experienced FGM, true, but I have experienced male oppression and sexism and all the rest of it. I would never think to say eg to an organisation helping people who are deaf, that I completely understand where they are coming from, and in fact I should be able to tell them what to think, on the basis that I am female and have experienced discrimination on that basis. It's silly.
By all means trans feminists please do feel free to fight for causes which help women everywhere (although from the manifesto that doesn't seem to be something that is called for) and through my general activities hopefully all women will be helped including trans women. But don't tell me that loads of things which are important to women are irrelevant, and that I should turn my back on them to work towards a very specific set of aims that will help a very very small number of trans women.
