You make wonderful points and articulate them clearly. However, I did cringe a bit at the quote from Astra Taylor : "Always from a white man." I guess she never spoke with Clarence Thomas.
She's using the race of the proponents to attack an idea. Which is racist itself. But the idea, as you articulate, is loathsome and inane regardless of who is pushing it. The Republican party, as exemplified by the 2020 summer convention, loves to trot out token minorities in a usually futile attempt to show that they are not racists. https://dockruse.medium.com/republicans-unlinked-from-lincoln-99d5cc949ce8
