Okay, I'll break the analogy down for you, since you are having a hard time:
Part one: You, me, the writer (any human being)
Part two: Existing in a public space (to be found via Google or or noticed in Twitter or making stuff on Etsy or showing things on Instagram or just being photographed in person)
Part three: Self-expression of any form (writing something that will be found "colonial," or a blog, or making a hand gesture, cracking one's knuckles, or standing there with an uncomfortable smile, or even knitting (https://unherd.com/2020/01/cast-out-how-knitting-fell-into-a...) in that public space
Part four: Negative consequence for that self-expression ("cancelled," getting fired, the usual death threats, "screaming, hats first into the wood chipper") from ... people who have never even met you, who found that self-expression in the public space.
Cardinal Richelieu: "If one would give me six lines written by the hand of the most honest man, I would find something in them to have him hanged."
It's the revolutionary spirit of the times. These incidents occur. You may not be aware of them, but others are aware of them, and they have what is known as a chilling effect.
