These comments were echoed by teacher and author Nathan Tidridge, who asserted that, beginning in the 1960s, the role of the Crown disappeared from provincial education curricula, as the general subject of civics came to receive less attention. He said Canadians are being "educated to be illiterate, ambivalent, or even hostile toward our constitutional monarchy". Michael Valpy also pointed to the fact that "The crown's role in the machinery of Canada's constitutional monarchy rarely sees daylight. Only a handful of times in our history has it been subjected to glaring sunshine, unfortunately resulting in a black hole of public understanding as to how it works." He later iterated: "the public's attention span on the constitutional intricacies of the monarchy is clinically short".
