The current fashion is to refer to the treatment of Canada's Indigenous people as "cultural genocide". "Genocide" is a highly charged term referring to mass brutal killings of the 20th century (e.g. Armenians by Turks or Jews and Gypsies by Nazi Germany).

"Genocide" might also be applied to the mass killings of indigenous peoples in the USA by American troops and settlers.

It is worth recalling that, after Little Big Horn, Sitting Bull led his Lakota tribe into Saskatchewan in Canada for refuge in 1876 where they stayed for 5 years. During much of the time the Lakota sought refuge in Canada, Sir John A. MacDonald was Canada's Prime Minister.  Sitting Bull was able to judge just who threatened "genocide" and who didn't.

Canadian residential schools were a cultural disaster as is the continuing racial discrimination and inferior health services indigenous peoples suffer in Canada.

Removing Sir John's name lacks the historical perspective our schools should impart to their students.
