But all women have different needs. I think it's better to point out that transwomen don't face the same disadvantages that some natal women do as a result of their female bodies. Our bodies are the things that make us most vulnerable especially re childbirth and the aftermath, PND, pressure to breastfeed, likelihood of staying home to raise the child and therefore become financially dependant on your husband/wife etc.
I've seen feminists try to make these softly-softly arguments, and it ALWAYS goes badly. The TRAs just retort 'not all women have children, are you saying childless women aren't women, you are reducing women to breeders, how regressive and misogynist of you.'
Saying that 'transwomen' (aka men) have 'different needs' to 'natal women' (aka women) never works. Because it is disingenuous and skirts the main issue, which is that the world is hierarchically organised according to sex, and all women, whether they have children or not, are born into the female sex caste, and this impacts every aspect of our lives, even though we are otherwise a very broad group with different life experiences.
Femme-presenting men are not female, they are never treated as female, and if they are discriminated against it is because of homophobia, not sexism. Further, just because a man presents in a feminine manner, it does not mean that he has rejected masculinity; indeed anyone with enough exposure to trans-identified males can see that many are aggressively male dominant and virulently misogynistic.
So saying that our needs are different is misleading, and hides the fact that the needs of women and TIMs are not just 'different' but antithetical. Women need to get rid of femininity for our liberation, TIMs need to shore it up otherwise they'd have nothing with which to signal their 'womanhood'. Women want an end to the portrayal of us as objects for sexual use, many TIMs get off on being portrayed as helpless fuck objects and this is where their cross-dressing fetish started (google sissy porn if you dare). Women need to be recognised as a distinct class of persons in order for sexism to be tackled, TIMs need to obliterate the meaning of 'woman' so that it can include them. And so on.
