People have this problem where they subscribe to Us versus Them thinking. They dehumanize certain groups of people and see them as something less than human, and therefore they don't care if they are harmed. Militaries all over the globe do this to train their armies to kill without discrimination.
We see it in the USA all the time with the two party political system. I think if the extremist liberals and extremist conservatives had to share a room, it would turn into a blood bath before any common ground could be found. It's disappointing and disturbing to me that people can't seem to act in a civil manner. People get tunnel vision and lose sight of the fact that we all have to share this planet and we have to compromise on a lot of things. Seems like most people don't want to compromise anymore, they want to destroy the opposing side instead and rule the world. That's so delusional I can't even...
