white feminists have been racist as fuck since forever. like even back to first wave suffragists, the movement literally split in two because they were upset that black men got the vote before white women (suffragists were highly involved with abolitionism, the contention was with the 14th Amendment)
Like #1 said, there's sadly a long tradition of racism within the movement. In addition, there's also discrimination against LGBT people, to the point it's not uncommon to see specific terms for these bigots like TERF (Trans Exclusionary Radical Feminist, also spelled "terf") in discussions about transitioning and feminism.
