To repeat what I said yesterday, racism is stereotyping. If Mark, in his greying years, can’t avoid thinking in stereotypes, then yes, he’s becoming dumb (and conservative). This is a liability against which aging persons like GBT and myself have to be on guard.
Let me just add here that a cartoonist’s stereotypes like GBT’s won’t become racist so long as Trudeau and his readers recognize them as stereotypes. If you really thought that Ray, for instance, stood for all black soldiers, or that Becca Bickle represented all female intellectuals, you’d be a racist stereotyper. (Sorry, the noun doesn’t exist; I had to make it up.)
