What this is really about is anger and resentment from those born male that biological females do not have to do anything to be perceived as and have bodies that work as female. Biological males on the other hand have to do a great deal to get others to perceive them as female and do not have the biology they feel they should have, and this is seen as a disadvantaged womanhood to those who believe that TWAW.
The anger from biological females is that this has absolutely no awareness or comprehension of the fundamental disadvantage of being female, and the inequality of being female, all of which are based solely on being born with female biology. They cannot be identified out of, in the way that the language, concepts and resources of womanhood can now be identified into by those without that fundamental biological disadvantage. To female people it can feel rather like being a wheelchair user facing someone furiously distressed, angry and blaming that they don't have a wheelchair too and would really like to have one and not be able to walk. The language to talk to each other, to share the experience of being female, to seek support or resources to address the specific disadvantages of female biology are now suddenly supposed to be seen on their part as acts of aggression, because they fail to centre the feelings and needs of biological males.
Those born male can have no concept of what these disadvantages and oppressions of having female biology really are, and this is helped along because a) they have the male biological and trans experience, not the female one, and b) because it isn't relevant, and male socialisation and an unequal society makes it automatic for males not to need to be aware of or care about issues that don't affect them.
As a result, it can come across as fundamental and unreasonable male anger with females just for being female, as this constantly reminds that there is a meaningful difference in being born female and born male and that this is a reality no matter how distressing it is to face or how much people are encouraged to change language and spaces to conceal it. And often this appears to wish some sort of ill fate or sacrifice or visible loss on the part of female people in the form of payment for their natural and so unfair good fortune.
To female people, this can seem just more of the same entitled, oppressive, dominating and tone deaf behaviour from males they are so very used to, earned solely by the bad luck of having been conceived a biological female.
Its not a win-win bit of language.
