As a Moderator, I agree with Erich 100%.... As I have said twice before, some may find it offensive for very valid reasons, and I dont think poking fun at them and saying "get over it" is the correct way of putting it Twitch.... If it becomes much more of an issue, I would recommend to SS Tiger that he shorten his nickname as well....
My Grandfather hated the Japanese, dispised them, and carried that feeling to his grave.... If u told him to get over it, he'd punch ur fuckin lights out till Tuesday...
