The op said that the offensive word was used against the bishop country. So it wasn't directed to anybody in particular. That's exactly the context of what you might hear in real life. The way people talk. It's not meant to be a slur to personally hurt somebody. It's something someone says. It's almost an adjective these days. And everybody knows that, except for the Opie I guess.
Nevertheless, of course that kind of talk is not allowed in the game. I would like to see a screenshot to even make sure that he's telling the truth to be honest.
But we know that the moderators do a great job in the game.
Now the op also is known to personally attack people in the game, as shown by the screenshot. And also on this forum here in this thread. Personal attacks directed at a person.
If he really is 15 years old, maybe his mother should supervise his game time and shield him from things that upset him. I mean he's still a child. Maybe you shouldn't even be playing on the internet until he's a little more mature.
