Foucault and the Postmodern philosophers of the 70s started this, with a new epistemology that ties language use to our perceptions of reality, and also the idea of how marginalized people remain marginalized. You see, the power matrix operates daily and we are all involved. We perpetuate real world problems with problematic language, we are told.

Change the language, change the outcome, came the activists of the 90s and 2000's. This stuff somehow spilled out of literary theory in academia and started becoming a political force for understanding power dynamics. You can get a taste below, where the commenter is comparing black and white concepts, and how we view one as good and another as bad.

Do these folks (like the commenter below) have a point? Yes, sure. But submit your point to the marketplace of ideas instead of trying to force people's hands through censorship. Not everyone has to buy social constructivism. We're allowed to believe that racism has material and economic causes, and changing it has minimally to do with language. So no, don't make me change my git default branch or the way I talk.
