Racism is a lie. Racism is doublethink. After "multiracial whiteness" it should be obvious that "racism" is simultaneously a difference of opinion independent of the color of people's skin and a propaganda tool dependent solely on the color of people's skin.

Grieve. Be outraged. But do not let yourself be trapped arguing doublethink with BLM. It contradicts itself. Everything against it is also for it, everything for it is also against it, and everything you say will reinforce their opinions in their own minds.
