In recent weeks, as stories about Idle No More or rape in India have populated our news media, I’ve been reminded yet again that differences in culture can’t be boiled down to pat clichés about cuisine, but are instead about ways of understanding the world. The tension lingering around divisions between cultural groups seems more present than usual, and I half expect that at any moment the city’s ethnic groups might break out into 1950s-style street fight replete with switchblades and greased hair.
