The Last Battle
Experience tells us that people do not think the same way. One person looks at someone or something and calls it good. Another person looks at the same person or thing and calls it bad.
The Star Trek episode called "Let That Be Your Last Battlefield" shows two people who continue fighting even after their cities burned. Perhaps one of these guys could be called "The Blue" and the other called "The Red".
Experience tells us that there is little point trying to convince people of the opposite mentality that they are wrong.
Social groups such as workplaces, schools, and churches often have a policy that talking about politics or maybe any personal beliefs is forbidden.
People often move to another city so they can be among people of the same mentality.
It can be difficult to live in a "Mixed Mentality" area!
Someone pointed out that the real battle is not between Red and Blue; it is between the Rich and You!
