This is my take-
Everyone can write (or paint, or sing) from the perspective or about anyone else. And anyone who says otherwise is just trying to control you.
I am also bored to fucking tears from talking & reading about race. It’s gone from valid grievances, life or death issues, to “I’m mad that some people disagree with me”. You don’t improve race relations by blocking a racist on twitter- we have to get off our asses and tackle it at an institutional level.
Finally, you are absolutely allowed to talk about these things, cause racism also affects white people, just make sure your communication is 80% listening.
