Jesus. The details are damning. This is not white Gen-Z'ers thinking they're post-racial so they can repeat the stuff they hear from black content creators (and of course, they're not and they shouldn't). This is pretty much old-school racism.
Also apparently not the first issue, or the second.
What (or who?) could create a corporate culture where racists would feel empowered to say anything they want without fear of repercussion?
