Underneath the argument about social cohesion is one assumption that needs questioning. It is the belief that what provides cohesion and coherence in any given society is ethnicity. If we can retain just enough ethnic uniformity, runs the argument, then we can hope that society can just about hold together. Threaten that ethnic cohesion with too much diversity, and the whole thing will come crashing down in the chaos of racial and tribal conflict. And there is evidence that if that is all we do ”” extend the ethnic mix ”” social conflict can and often does arise.
The reality is that ethnic diversity runs not just between ethnic groups, but within ourselves. Very few of us are ethnically monochrome. We are all basically migrants. My own mother came over from Ireland to England in the 1940s. Her ancestors were refugees fleeing 17th-century religious persecution in the Rhineland. Everyone, somewhere in their ancestral history, has a connection to someone who lived somewhere else. All of us are the beneficiaries of the generosity of this country or of others, at a time when our ancestors were in desperate need of shelter, safety or simply wanting a better life.
The evidence suggests that ethnic uniformity does not create social cohesion. Historically and politically, nations that strive towards ethnic uniformity have often proven to be unstable and unsustainable. The very Middle Eastern countries in so much turmoil at the moment are more ethnically and religiously uniform than ours, with much lower rates of immigration, yet are riven with far more internal conflict than diverse societies such as the UK.
