My son was, too. I didn’t raise him strictly (I was a hippie mother, raised in the 70s), but gradually acclimatised him through smaller interactions (small groups to larger, to regional to public), because I had that luxury. Lots of parents over the past 10 years were deprived of that, and it’s been exceptionally difficult to get a child acclimatised to an increasingly hostile world.
People have been far less patient in public – which is entirely understandable, given the circumstances – so many parents and other caregivers (teachers, counsellors, etc) who are trying their best can’t help but be defensive when they hear negativity towards children online, because I’d wager everyone encounters people who are excessively put out by the slightest transgression of a child in their proximity.
It may not be the way the majority react, nor how you react, but it happens regularly enough to become exhausting.
So, in these conversations, I feel like many people are responding to children who are clearly being publicly misparented, and then there are many parents who are thinking of the times someone overreacted to a social faux pas by their child.
I feel like people are misdirecting their anger here.
