I mean, I understand what you're saying. I guess the main way I can explain it isn't in any idealized case, but in the transitional case.
I completely agree that people might not be looking for a solution in a discussion. My point is that transitioning from a place where there are plenty of people, having plenty of discussions, and ideas flow freely back and forth is normal and welcome. And then moving to a place where people have plenty of discussions, but more often than not, ideas flowing back and forth are treated with outright hostility...
I mean, for me, it was very obviously a completely jarring transition. It's not that there are times when solutions aren't welcome. It's that the vast majority of the time, with the vast majority of people, alternative paradigms aren't welcome.
I suppose I’ve found myself lucky when many* people are open to new and even contradictory ideas, one on one**, and when they feel respected and calm.
* but definitely not all
** because there’s no more ego, status nor hierarchy to defend.
