Comment: "When you start running out of ideas to change the present, you start messing with the past, history, past figures and Canadian traditions."
Unbelievable!!!
Did you even read the article? The author has ideas to change the present. The whole premise of this piece is about dealing with "present" issues.
You, and others, as he suggests, are just not listening, or do not want to listen.
He lists a few legitimate "present" concerns: 
"slow implementation of recommendations made by the inquiry investigating the death of seven First Nations youth in Thunder Bay; and we’ve seen the grieving family of Barbara Kentner, the First Nations victim in a racially motivated killing, forced to flee their homes because of threats made against their children at school."
Your complete inability, or desire, to understand what he is saying suggests you come to the discussion with a mind already made up.
That is the problem.
