I didn't mean to imply that all the marginalized professors would be immediately fired the day after tenure was abolished. Indeed, many of them will have nothing to fear as long as they kept their mouths shut. But the purpose of tenure is to give academics the freedom to speak the truth to power. No one is going to need that freedom more than recently hired professors from marginalized communities, especially those who are trying to reform the inequities that arise from traditions designed to protect privilege.

I've done a lot of research on what is called racism and sexism in my attempts to rectify the blindness that inevitably arises from my being privileged. From my experience almost anything can be seen as racist or sexist by somebody. Of course racism and sexism are real, but they are hard to define and heavily dependent on immeasurable things like voice tone and context. That's why they would be easily exploited by people in power looking to fire trouble makers.
