On what in particular? Because Google is full of information, studies, and articles on the white supremacy within feminism from it’s beginning to current. One perspective that is left out is the perspective of black men and that is often silenced and erased by black feminists and white feminists. So, simply reading studies, articles and opinion pieces by actual feminists as well as by black men who suffer at the hands of feminism, and not to mention articles on the history of white supremacy within feminism is a good start.
I could list link after link, but I have done that in a number of threads on this same subject. So, if you looked past them, then I would suggest just googling and starting your own journey to learn more.
What I find most interesting, is that any other movement/ideology with a history of white supremacy, sexism, and hatred/contempt for black people (or any people for that matter) would easily be put in the position of a hate group. But, because it was started by predominantly rich/connected white women, it just seems to be given a pass.
