I've only ever met a handful of people who seriously maintained this, but it was the insistence and hysteria with which they did so, and the overwhelming agreement/support in their in-group that was the most disturbing.
There are cliques of basketcases around, where brain-eating ideas have taken hold.
Of all the stupid ideas that have emerged in recent years, there may be none worse than the insistence that unwelcome words are the same as violence. This false perception equates physical acts that can injure or kill people with disagreements and insults that might cause hurt feelings and potentially justifies responding to the latter with the former.
"Ninety one percent of undergraduate students believe that words can be violence, according to a new poll by the Foundation for Individual Rights and Expression [FIRE] and College Pulse," FIRE announced last week.
Fully 22% of survey respondents completely agreed with the notion that words can be violence (with another 25% saying "mostly" and 28% saying "somewhat"). Can't always derive too much from these things, since what the respondents actually mean isn't always clear (hedge, misinterpret question, social desirability bias etc, etc).
We've seen the cognitive and emotional decay for a while:
In 2017, when the conflation of words and violence was relatively new, Jonathan Haidt, a New York University psychology professor, worried that the false equivalence fed into the simmering mental health crisis among young people. He and FIRE President Greg Lukianoff wrote in The Atlantic that "growing numbers of college students have become less able to cope with the challenges of campus life, including offensive ideas, insensitive professors, and rude or even racist and sexist peers"
It's terrifying enough that there are any people, let alone university-educated, "smart" ones, who believe this. All I have for them is, ironically, a punch in the face.
