Speak White
"Speak White" was an insult used by Anglos against Francophones in Canada when the Francophone were speaking French in public. For example, a francophone in Québec customer could get the reply "Speak White" simply for saying "Bonjour" while entering an Anglo owned shop.
Based on this insult, Québec poet Michèle Lalonde wrote a poem with the same name. Her poem was based on the daily reality of Canada's Francophones during the 70's and before.
Pierre Falardeau and Julien Poulin, two Québec-based film producers, created in 1980 a short film based on Michèle Lalonde's poem.
