I understand if you disagree on whether, by expecting children to go without respect and people to submit to the natural hierarchy, their comment promotes a form of child abuse. But do you disapprove of the methods or of the choice of target?
If it is the methods, do you want me to report everyone who makes similarly rude statements about fossil fuel companies so you can ask them to tone it down a little? Because fossil fuel companies too are neither outlandish nor hateful. Perhaps even about right-wing politicians? Many of them are hateful, but is it really right for us to act disrespectfully in turn?
If it is the choice of target, then would you please add a clarification to the rules where you outline what determines who is a valid target?
I'm frankly confused about your second paragraph. Do you have a different definition of "definition"? Because I didn't give a definition, I did not mean human rights, and the notion that respect can and should be earned also isn't a definition. I and your "common understanding" only give two different priors for who deserves respect.
Is it so hard to fathom the notion of actually respecting children? Because I mean actual respect. Feeling the same gravitas at your infant child who wants a cookie before bedtime as at a CEO who wants that report on their desk by tomorrow morning when you clock out in five minutes, and vice versa. Just two people who have their own unstated reasons for wanting something that from your perspective appears unreasonable. The only difference is that the state uses its monopoly on violence to enable you to abuse one and enable the other to abuse you.
People will often find themselves in the position where they're forced to accept abuse from others, but that doesn't make it right for them to pass it on, and it doesn't make it right for them to claim that the abuse is fair or compatible with anarchism.
As far as I've seen, it's rare to find someone for who "having earned their respect" isn't code for someone having power over them, and for who "not having earned their respect" isn't code for them having power over someone.
I mean, can you or can you not picture your job being done by a pig wearing clothes in a children's book?
Because I can picture a pig with a boater hat and round glasses carrying a pile of half-unspooled film reels, a pair of safety scissors and a roll of tape on their belt.
And before you complain about it being an old-fashioned depiction, the OOP isn't exactly how a modern butcher works either.
