They have a point: Mr Trudeau  has decided the Langevin block  named after Hector-Louis Langevin, a father of Confederation and MacDonald cabinet member will be renamed.  Langevin proposed the creation of the residential school system as the quickest way to "assimilate" First Nations children into Euro-Canadian society.  So if  the  good teachers  now use Orwellian NewSpeak to rewrite inconvenient history don't stop with Sir John. To eliminate our historical chronicle of "Final Solution" ( Canadian Ministerial jargon from the 1920's, not what you are thinking) to the "Indian Problem"  perhaps they  could wipe out  the Indian Act (R.S.C., 1985, c. I-5).  Let's really get down to root causes and all head back to to the "Old Country" where we can start wiping out all evidence of the horrible repressing acts  we did to each other over there for,  well actually  for ever.  Having removed all history we have acheived something else too, no need for teachers.
