Actually, you are misunderstanding the paradox of tolerance. And I would say it is one of the most frequently misquoted philosophy on discussion forums such as lemmy or reddit.
Popper asserted many times that the intolerable intolerance is violence. “Fists and pistols” as he calls it.
By intolerating at a stage by calling the other as intolerable when we’re still quite far from violence such as this case of HR management, you are proposing for an unjust society–is what Popper would say.
