There is an angle to it that is not that obvious. The kids have been part of social media and they consult each other and then they go couch surfing upon a disagreement. So saying no is like saying no to a group of people with the same agenda and viewpoint and they would retaliate. Like Lord Of the Flies.

I tend to find all sorts of generalizations like this so useless. Like, this thing you said seems totally random to me. I know lots of "elder millennial" parents and lots of parents of other ages, and I see lots of variation between parents in "not saying no", but I don't see any correlation by age... Regional and political cultural differences are way more correlated with things like this IMO.
