Saying you cant say a word purely based on skin color is text book racism because ti discriminates on skin color race and ethnicity. Also saying that anyone using ut just want to be edgy or offensive is also a bad take since they might just not have american culture values
I met someone who had such a thought about hatespeech and how you should be fined until I pointed out he and his friends call eachother retarded removeds on discord all the time and asked how much he should have to pay in fines. He stopped supporting the idea of fines
In my opinion its impossible to be unable to care less if you are aware of something there is always a tiny bit of care wether its negative or not is irrelevant.
I dont think I understand your last point
Either way not everyone shares american values or definitions when it comes to words
