"Mr. Dion joined several Liberal MPs in heckling Mr. Cooper. Mr. Dion then gave the thumbs down."

“If I expressed my disregard to the member very strongly, it is because I mean it.”

So this would be the more polite, respectful parliament Mr. Trudeau promised? And the statement by the Liberal that Dion was forced into it by "the tone" of the question he was asked... forgive me but is Dion 5 years old? Because that's about the age when I'd expect that is no longer to be offered as an excuse.
