Seeing all the TERFs/SWERFs made me wonder, has there been [B]lack [E]xclusionary [R]adical [F]eminists in the past?

This brings to mind Sojourner Truth's Ain't I A Woman speech. She was a slave who escaped her master and became an activist. She gave that speech at a convention to a crowd of white women who didn't want her speak because they wanted to keep the feminist movement separate from abolition.
