Whatever you may think of David Climenhaga (I personally think he's fairly honest)
This kind of silent dog-whistling, though, is nothing new for Mr. Kenney. Indeed, it’s among his go-to techniques.
Consider, in the recent past:
His “corrosive” social media misrepresentation of an Islamic religious ceremony.
His accusation that “people like” Calgary Mayor Naheed Nenshi were “politicizing” the niqab controversy his own party had ginned up for political purposes during the 2015 federal election.
His Tweet suggesting Indigenous people are just “settlers” too.
His characterization of “perfect, unaccented English” as an essential quality of being Canadian.
His catcalls in Parliament mocking the minister of national defence’s manner of speaking by demanding “English-to-English translation.”
