No, it's not. I have black friends that get offended by the word whenever another black person says it too. The person saying the word doesn't change the fact that the word is horrible and needs to disappear, not be used as slant by a certain group of people
If a black person say it, it's like saying "my fellow black person" or "my brother.". It's a comraderie thing. So if someone who isn't black says it, it's not alright because you're not black and you don't know what black people go through. Some don't like it when anybody says the word because it reminds them of slavery and Jim Crow
And I'm not saying it's ok for white people to use it either (I agree it's even worse if they use it). What I'm saying is that the word should stop being used altogether because of how offensive it is.
The point is that it's only offensive if you say it and you're not black. What are you not getting? Lol
