What do we still not understand about blackface?

You would think that after so much "listening and learning" by white people over the past few years, we'd stop seeing them wearing blackface in Canada. But it still happens. Relatively often.

Why do Canadians consider this an American phenomenon? What's the history of blackface in this country? And how can we provide the proper context to explain why it's so awful?
