This is a rabbit hole if we go back and forth. Yes, there was always a get-off-my-lawn element in previous generations. But I am trying to hone in on certain critiques that are valid for certain generations. I'll give in you an example:

It was (whether the generation was self aware or not) mostly acceptably for people in America in the 1950s to be mildly racist towards black people (it's just, how they grew up, it was the status quo). That's not a get-off-my-lawn observation of that demographic. This was not a simple generational "quirk", it was a notable flaw.

Socially, I think somethings a little up with whatever is going on now days. But that's just me and history will sort this. Things are very hard to sort out as it's actually happening.
