> One of the things I find interesting about classifying literally any kind of trait within bounds of 'normality', and the culling / suppressing / discouragement of anything outside of that definition, is that there will just be new 'edges'

There is a general rule I've discovered many years ago, through playing EVE ONLINE and learning understanding how society works. Not the modern EVE ONLINE, the old EVE ONLINE. It was really good for that.

Every new generation grows up with a new norm. Whenever hardship or challenges are being removed, then the new generation, having never needed to learn how to deal with them, will have a lower tolerance of them in general.

Your "new edges" generally aren't actually new. They've always been there. It was just that nobody really cared, because they weren't the end of the world: People knew worse.

It's a self-destructive downwards spiral.
