Many Canadian media types as well as Mr MacDougall are slow in the uptake and looking too hard for something  to cry about...
 This remark " What is it about Mr. Trudeau that turns foreign reporters into crack addicts? whines Mr MacDougall:
“His dark hair is a colour found in nature,” Stephen Rodrick, the Rolling Stone reporter, squeals in his piece."
Is meant as a contrast to Trumps orange face and hair-colours not found in nature -

 However in looking too hard for  fault fining Macdougall has completely missed the point. It is not Rolling Stone who is doing the squealing.
