I'm siding with OP on this one. Exper looked like he was the one who provoked everything, and Placid looks like he's groping around for "evidence" of sk8 being stupid, whilst saying "handicapped" every three words.
I'm not saying sk8GameFreak is not ignorant, but it seems to me that this wasn't his doing, and he also handles Exper attempting to troll him via IRC better than usual.
