I think the idea that politicians sow division and without them we'd all get along fine is quite naive. Probably because the rise of the Nazis is so prevalent in our education and media. I think history shows the opposite - a state's elite has an interest in different ethnic or religious groups getting along, but things tend to unravel anyway when the shit hits the fan, especially in times of economic hardship. The English of course are confident that these things happen only in backward countries east of Vienna.
