I think it's fair to say that trans women - assigned male at birth - are not biologically women.
But if they identify as women, they are going to face the same discrimination and harassment that biological women suffer. In that respect, we are united.
However, transgenderism has it's own culture and faces different problems to those experienced by biological women.
Both women and trans women are sheltering under the same umbrella, but we are innately two different groups, even though both will sometimes share the same experiences.
I can be standing side by side with a black woman - both of us experiencing discrimination as women. But her experiences will be different from mine. Our unity is in the fact that we both suffer discrimination. And I believe that this is also the case with trans women / biological women. Neither group will have exactly the same experiences as 'women'.
How much we identify with each other is always going to be questionable - and therefore a continuing problem. Some see trans women as male activists dictating terms to women. Maybe some are but equally there must be those who simply want to be identified as women because they identify as women.
It's complex.

Why is her transformation less valid than a transwomen's? Yes she lied about her ethnic roots, but then again transracial self ID isn't generally accepted so I suppose she felt she had to. Inclusivity would demand she should be accepted into the black community "she is what she says she is" is the mantra isn't it?
