Not needing to eat would definitely be a huge strength.
Having a pawn attack a square near your king is a weakness. Being an air hockey player should mean that doesn't matter.
Crying IS the mental breakdown. It's what you do when you need someone else's help because you can't do it yourself(weakness).
The problem here is that people prey on you when they see that weakness, and a civilized society should not do this. The problem here is that we're developing all of the tools for a civilized society and putting them into the hands of predators. A weakness is only a problem when it's being exploited. This is why I oppose usage of things that give our predatory "leaders" leverage against us that we can't escape. Surveillance bad. Censorship bad. Detention bad.
I didn't say emotions were a weakness. They're actually a defense mechanism. You kinda describe it like a production line run by robots that you totally can't stop. Just let them make their products.
