I find that boxed thinking quite problematic. Plenty of great solutions came without loyalty or optimism. Why did we throw positive thinking into the mix of otherwise confrontantional systems.

I say confrontational systems, because the only way to actually spark change in a system that has been systematically extinguishing sparks of change is actually confrontation. And the very fact that confrontation as such is now associated with negative emotion (same with conflict actually) goes hand in hand with the top level comment on this issue. Confrontation/conflict is bad, optimism is good.

Confrontration is how you bring attention to a problem. Conflict is what happens when that dominant idea is challenged by another idea.
