I wouldn't use the word bigotry.

"He's arrogant, he's pompous,he's opinionated and he believes that everything he says is right, he drives at the Irish to provoke a reaction. "And he does know what he's doing."

Sorry but I feel any derogatory remarks against Keith were sadly self inflicted. His desire to invite the Irish and give them a bloody nose may have caused him to experience anger, frustration and despair when they ignored him.
