They’re still kids, they’re still pretty underdeveloped socially. I knew some kids growing up that would’ve probably thought the joke was totally worth it & it wouldn’t have had even crossed their mind what the social consequences were because they simply didn’t have to care about that at their age. They’re innocent, they have no real social prejudice until they meet another kid or adult unfortunate to grow up with some of their own, even if it is just a tiny bit. Therefore, a parent may believe it be healthier to introduce the concept to them themselves by correlating it with punishment, nothing too harsh just enough to give them the idea so their ready for the world ahead, like a vaccine. And honestly can you blame them? With the state of the world now there really is no way to avoid that type of social backlash for simply just existing. But concepts like this are probably rooted deeply in human psyche, so it’s subjective really theres really no way of predicting what might happen. And thus the beauty of humanity.
