N word usage

My school [american] is 50% hispanic 50% white, just about literally everyone uses the n word including hard r, obviously not with any racist intent, theres literally nobody to even be racist to by using it, is it really wrong to use it? I mean we used to have a couple black kids at our school who obviously didnt give af about people saying it, I feel like if you are offended by it then you yourself are literally choosing to be offended by it, or is my whole school just apparently racist?
