There's a huge strain of "mind your own business" running through the USA right now. When someone is out of line, you used to be able to rely on the public to correct that behavior. Now if you try, you're the bad guy--or "Karen" as they say, and everyone flips out their cell phone cameras to try to capture that crazed weirdo who has the audacity to ask someone else to behave themselves.
I brought my kid to a pumpkin patch for Halloween last year and this lady told her kids to simply cut in line so they can go do some fun thing first. I thought to myself "crap, I can't say anything because you know what'll happen." My elderly father didn't have that inner voice and told the lady to get her kids to the back of the line. Well, as I expected, lady totally went bananas, whipped out her cellphone, shouting "you don't talk to my kids!" calling my old man a racist... everything under the sun.
We're expected to simply sit back, mind our own business, and ignore bad/destructive behavior. If you believe in the social contract you're out of line.
