Well, my experience mirrors his, and I grew up in Montreal in the 1970s on a street that reflected the United Nations.  Anglos, francos, Jamaicans, Pakistanis, Philipinos, Japanese, Armenians, Chinese, Latinos, you name it, and we kids were apparently too ignorant of all the ways we were "distinct", "special" or "diverse", and just got along without having to be "validated".   Today, the SJWs would have us all check our privilege while we conducted an intersectional analysis to determine who was most "oppressed"...
