You completely missed my point, especially by your claim, “Creating different social rules based on skin color is racist.”
It’s not and never was a matter of race. It’s a matter of a group of human beings with experiences that only that group can know and appreciate. I pointed this out to you already, and did so in greater length in this article where I demonstrated the same dynamic applies to the military, to gender, and to other races. If you like, I can make the same argument about school-shooting survivors or regional cultures or even political parties.
Again, us whites (or any other non-black race) not being able to say the n-word isn’t about race, but about a group of human beings with experiences that only that group can know and appreciate.
