Racism, Misogyny and transphobia have always come from a similar place and build off of each other. They share the same narratives and the same desire for ostracization and oppression. Bigots will always ally with other bigots, as this hatred is not rational and only someone with similarly irrational hate could support you. Dig enough in bigoted communities and you are certain to find all different kinds of hatred.
That’s why TERF communities are infested with homophobia, misogyny, racism, antisemitism and Islamophobia. Over time the concentration of white supremacy and nazism has grown exponentially in terf communities. Nazis share many of the same goals and many of the same conspiracies that terfs do. And prominent terfs like Kelly Jay Keen openly ally with Christian white nationalists around the world.
