I recently traveled to Turkey and saw a living (actually NOT living) example of how importance diversity is. At the formation of the country of Turkey, there was a “population exchange” between Greece and Turkey. Christians were sent to Greece; Muslims were sent to Turkey. Christians and Muslims had lived peacefully together for generations. Towns lost the diversity in their populations. And, as a result, towns died. Difference works! It does not work to eliminate difference. The town of Kayakoy is a memorial to the importance of difference.
