Yes. She said clearly that the argument between you and An Gadai should be taken to the Pit instead of continuing in ATMB.
There is no board-wide rule against calling another poster a racist; it’s something we discourage in Great Debates. From what I can tell, tomndebb has been consistent on this point and I think I have, too. And you were posting in ATMB. While we don’t allow insults in ATMB, we have to give posters a little bit of latitude in asking questions about the rules. (For example you can’t call another poster a troll or a jerk in any forum except the Pit, but in ATMB you can link to a post or a thread and ask if a certain poster was trolling or being a jerk in that thread.)
