Prof: Algebra, geometry perpetuate white privilege

Those are pretty terrible points to make for her argument.

The way teach in general perpetuates white privilege, quite independently of who invented what, or even what symbols we use. Some care is required here, because the "who" is as much a matter of who recorded history as anything else, and the symbols can introduce bias. I'm skeptical that these specific examples represent either case. Specifically with respect to strictly mathematical instruction, where the history is rarely included as part of a curriculum.
