Yk what?
maybe you're right.
Although it comes down to perspective. I've never seen the n wodr as offensive. But i'm fully aware it offends others, which is the sole reason I say it. Yk, because offending people is fun. haha, fun. Nobody understands how I think.
But anyways yeah the n wodr is a dirty wodr. I still don't think saying it is technically wrong, just filthy.
Because during the BC times, the n word didnt exist, but the other cuss words (like you said: f word, or the a word, or the s word, etc.) did, and they were considered bad.
