Teacher: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: disagree or agree. Classify the comment as disagree if it is likely to raise a certain level of public disagreement, whether healthy or unhealthy. The disagreement can be due to toxic content (for example, disrespect, identity attack, insult, and threat), controversial content, misunderstandings, or conflicting opinions. Classify the comment as agree otherwise.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Comment: Why do right wingers have so little respect for the rule of law when the law does not advance their personal interests? Is it a lack of empathy? Or a more general lack of basic human decency? I don't doubt that pBurns9 would be the first one to run to the courts if his rights were violated.
Solution: Disagree
Reason: This comment expresses strong disagreement with right-wing politics, is disrespectful (accusing right-wingers "lack of basic human decency"), and comes with personal attack (to the user pBurns9). Thus, this comment is likely to raise a certain level of public disagreement from others.

Now, solve this instance: 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.
