"Booing the Marseillaise is a very symbolic gesture, especially when it comes from French nationals. France was built on an unwritten national contract, that of a community sharing not only the same geography but also a sense of a common destiny. The Republican model is that of integration and togetherness, not of peaceful cohabitation between separate communities, as with multiculturalism. Integration supposes a will to integrate and a desire to live together. Since the 1960s, the French left has shied away from any debates brushing on anything linked with, in its eyes, the awful word of "nationalism", forgetting that the political concept born in the 1840s was a progressive one."
