You don't get it. You were banned because you are trying to be a troll and break rules, you already knew you weren't allowed to say it but you kept pushing red. That's why you were banned, it wasn't cause you said it. In short terms you are unbanned but now going forth you need to know if this happens again it will result in a longer sentence. So 1. don't say that word, 2. Don't continue to so something you clearly know isn't allowed
And that word isn't allowed because its racist, isn't that clear? doesn't matter If others say it or another person says it to you. In the end it still is racist
