Humanity was designed to be separated along a multitude of lines..

Some cultures, races, ideologies etc. were never meant to mix, but to coexist separately in peace.

You cannot expect to assimilate others into your way of life, your society, culture, faith, race etc.

Throughout history conflict happens when the separation breaks down, and/or when one segment of humanity intends to impose its ways or will on others.

Evil will thrive in the environment of anger and hatred within the attempt to diversify populations.

There is only one way this can end ultimately...
