Do you think they weren't?
I've already said I don't they were insulting. The msg was directed at his realm mate's
game play, not his inherent goodness as a person.
I understand that reasonable people can disagree on where to draw the line between 'insult' and 'non-insult', but if the consensus is (seems to be) that calling someone an !@#$%^& is acceptable, I don't see how you can reconcile getting upset because Kai said that another player is "bad at the game".
If he had said, for example, "Your mother was a hamster, and your father smelled of elderberries," those would
fighting words.
