The Leftist demand for "hate" and "racism" far outstrips the supply, so they frequently manufacture it out of thin air (e.g., Jessie Smollett hate hoax) or interpret events like this one to fit their narrative, despite (as you note) a lack of evidence to justify that conclusion.
Meanwhile, in the trans-terrorism attack in Nashville, there is actual evidence that the murderer hated Christians -- but that was not well reported by the MSM. The manifesto is still not released. Instead, they focused on Tennessee's outlawing trans surgery for minors, implying that the murders were justified!
Leftists reflexively accuse anyone who doesn't adhere to their ideology of expressing "hate" and wish to censor it on that basis. At the same time, they try to justify demonstrably hateful expressions and actions that fit the dominant narrative, e.g., Trudeau labelling the truckers "racists" etc.
The vile tactics of the Southern Poverty Law Center are now replicated by every DEI office in every university. These apparatchiks are like the thought police planted in every factory and school in the Soviet Union, to ensure conformity to Party rule.
The fact that a university representative participates in this grotesquely partisan rhetoric should be sufficient to justify stripping the school of all public funding. As long as universities promote Leftist ideology and suppression of freedom of speech they are not legitimate institutions of higher learning.
Radical activists have hijacked education, government and all major institutions, much as happened in the 20th century in nations that succumbed to Communism. Our society is on the same trajectory, but this form of totalitarianism utilizes cultural Marxism rather than economic Marxism in order to seize power. It's effective because anyone who dissents can be labelled a bigot and silenced.
I am glad you are a voice of reason against this and hope your article is widely read by students, staff and faculty at U. Waterloo. It should be run by the student paper there as an opinion piece -- if they have the guts to run it.
I recall having a discussion in the late 80s with a philosopher there (long since retired) who expressed fear that "political correctness" as it was then known was a danger to society. I said no it was just "respecting" others. How naive I was then! I did not realize that "PC" word-policing was just the start of it.
Now everything is seen through a narrow ideological lens, which is the antithesis of the critical rational analysis that universities should be teaching. All the good teachers have been forced into retirement, for the most part, and taking their place are ideologues willing to enforce groupthink through what could properly be termed indoctrination and propaganda. It's not a true education. U. Waterloo should lose all funding if it continues on this path. Thanks for reporting on this.
