If all the people that get upset over not being able to use a word felt as strongly about ending actually harmful systemic racism, I dont think this would even be an issue. By getting very upset about an issue like this, you betray a lack of understanding of history and its implications on modern society, a lack empathy, and a lack of respect.
The average black person looks around and says: "I live in poverty, the vast vast majority of other people I see that look like me do too. Our schools are way underfunded, we are locked up based on skin color, the ones that manage to rise to the top and get an education still have a much harder time finding jobs, getting loans, housing and are still profiled looked down upon, and held to a much higher standard in order to be thought of as " normal". The magical negroes which pass testing are the anecdoctal examples that many whites use to tell themselves that they're not really racist, while ignoring everything else that might shakeup their worldview or disrupt privilege in any way. I see a populace who obviously doesn't give a fuck about us, which is overwhelmingly evident by simply walking out of my front door and looking around. And its been like that for as far back as my familial lineage can be traced. I don't need fancy arguments, I don't need the volumes upon volumes of statistics, I don't need an impassioned speech to tell me what reality is like. I walk out the front door and I can see how well regarded black people truly are. Its as plain as day."
Its entirely inappropriate to complain about how that person has extra privilege of being able to say a word that you cannot say. Like I said, it betrays a fundamental lack of empathy--which is really the crux of the problem. Try not to be part of the problem.
