"Microaggressions"- What you call assumptions, when you want to make something someone said or did racial. You have no way of knowing these people wouldn't have reacted the same to whites this way, and leave out context. The only one you can say is racism, and not even a 'microaggression,' at that, was the hair. That was simply just straight up racist.
I can see why all you single-race people hate each other. You lot are always lecturing, shaming, dismissing, and being miserable towards each other. It's saddening. I don't see how lectures will change anyone on either side. No one likes being talked at. Makes more sense to connect, than shame.
