Now, I am currently having a debate about why World Conquest Zvezda Plot is the best anime.
Acceptance as military strategy
The anime clearly shows acceptance being not only beneficial, but crucial to win wars.
A young girl Natalie is only interested in robots and technology and nothing else. This causes her to be mocked and rejected by other children, and even her own parents abandon her because how weird she is and how she makes them look bad.
Kate finds her and says to her "You are alone, so now you can do whatever you want. Will you join me and come on a quest with me to conquer the world?"
Kate accepted and protected Natalie, was always nice to her and never mocked her.
In return, Natalie gave technology to Zvezda which made Zvezda technologically much superior to its enemies, which was crucial for Zvezda winning the war in the anime.
So when society rejects someone, all they do is turn that someone into enemy of society, which is one of many great points this anime makes.
