A racial epithet was thrown at me and my family in parting by a homeless person last year while crossing the intersection in my neighborhood, which we shrugged off. This quote prompted the memory again, and I think that Asians in Western countries may remain silent also because causing a scene is, in general, considered "unseemly" when little is perceived to be gained. I originally felt this to be a rather rational response for anybody else (regardless of their race), but when placed against the backdrop of the Immigration and Nationality Act of '65 mentioned in the article, I'm considering a different response the next time, although I sincerely hopefully there won't be a next time.
Makes one almost laugh good-naturedly at serious and systematic Canadian Québécois policies devoted to keeping the French language alive in Canada. I much rather prefer intense debates around language over race.
EDIT: I grew up in the Middle East, where racism is overt. In Saudi Arabia (for example), your salary for the exact same job is to a large extent determined by your passport nationality. I grew up expecting it there; but it always give me pause when encountering racism in a Western country.
