You live in this cotton candy fairytale land, where people can be "brought together". They can't. There are too many factors involved that make people and cultures different that trying to "bring them together" will just lead into conflict. Look at the mass immigration into Europe as a recent example.
The 60s are over, the hippies were wrong and you people need to let it go.
Let people separate from the people they don't, and never will, like, and that is a step towards peace.
Most people are annoying anyway.
