"Agreeing to disagree" is the easy way out of an argumentation. I think the parent is right in that having to worry so much about how others see things is unproductive and toxic. There's such a diversity of sensitivities, having to cater to all of them is a fool's errand.

Yes of course but in this case you're just wrong. This is a very well documented pattern of behavior at this point. Fortunately you're not my boss or colleague and so you can continue to promulgate these structures that cause a lot of misery and distress and lost productivity and I will continue to avoid being subject to them.
