I need your opinion :)

So I've only been here for around 9 months. I have never experienced this type of situation before so I was a bit baffled. Before I tell you this lemme just say I am not personally black, I am Hispanic, I also fully support BLM and many other movements. I was reading a manhwa when I suddenly see the n-word being used by an (Asian) character. Now I don't know If this is common or if maybe I overreacted because I posted a topic on how shocked I was and said that I don't think that was necessary or right even if the translator was a black person. But of course, got a negative reply as a result saying that "it's an illegal site" and that I should "stop obsessing over the n-word like it’s your whole identity". Now here's where your part comes in. Am I overreacting?

(Not threats not curse words but with facts and respectful thoughts cause that doesn't really seem to happen on this site cause it's just mostly dicks)
