I will disagree. The definition of humanity might vary person to person, but the core ideas will be same mostly; some will treat it to extreme level which includes all living beings, and some will consider it for humans only. But the values on which both of thought processes are based should be same or mostly same. It only differs slightly, not drastically according to what I know of the term. I only believe in Will of Steel, where we possess indomitable will. Apart from that our spirit should be like steel.
While writing this, I remember that my friend explained me a concept related to this by giving the example of Cyrus in Sinnoh. Cyrus also wanted a world where all people are like machine and emotionless, but the reason why he thought that was the fact that he also experienced some events which triggered his emotions. All living things respond to events happening with them or around them, even plants also respond to how people treat them. So being like machine is not at possible, and neither is desirable.
Discussing concepts with friends is a powerful way to reinforce our own understanding of the topic, plus we can also gain new insight for the same.
