Right, and if their child does only occasionally act out (as literally all children do at least a few times in their life), they might assume a commenter is that one guy who is overly put out over a minor social infraction, because just like you’re picturing the stand-out moments you’ve seen when it was bad, so are they. But their stand-out has been someone confronting you because your* eldest started stacking boxes in the aisle whilst you were tending to the baby for 30 seconds.
We’re all thinking of our own extremes and are kinda talking past each other. It seems that, unlike some conversations lately, everyone is kinda right, but it also seems that we need more empathy towards the fact that raising young children has been more societally difficult lately, and kids need less hostility to become emotionally healthy adults.
