Oh purlease. Wheeling this white feminism wibble out when you don't have a logical leg to stand on, it's so tiresome.
Feminism is about females and unites all the females in the world. I may be white, but I am no more or less female than any other woman. We are all female and we all share the same sex-based oppression, that is why the male-female power and control structures are so similar around the world, in almost all cultures. That is WHY it's important for women to support each other snd stand together. Male oppression of females cuts across ethnicity, culture, class, wealth, age, and pretty much any other grouping you can think of.
Making up that because the category of female doesn't include males, that anyone is excluding particular groups of females from it is desperate. And the way you seem to think "intersectional" feminism is about not being white, shows clearly that you see white as the default, despite white being a minority globally. Maybe you don't understand that there are powerful feminist movements around the world and women have defied oppression and stereotyping since ancient times, and many of them were not white, as you would expect.
