Haha.
This is why academics and idealists must be mocked without regard when they come up with idiotisms like this.
They did that in Africa: they created some arbitrary country lines without regards for the local tribes. The results? Constant political fighting and wars because you now forced two tribes which hated each other with a force of a thousand suns into the same new country.
So it wasn't "left" vs "right" but "Triba A" vs "Tribe B". No chance they'd get togather or that people would move from triba A to B because of some "political" opinion. It was more like blood revenge.
The belief that you could force two hating cultures into loving each other because you draw up some arbitrary lines on the map and say "now get well together, children" is [redacted] to say the least.
