It takes but simple logic to see that for a people to survive as a distinct cultural group they must have their own land so that their own ways can be furthered to the exclusion of alternate ways of life within that specific geographic territory.

Would you care to give any examples of this simple and straightforward process? I'll give you a few to get started: South Africa, Israel, Croatia, Serbia, Kosovo, Nagorno-Karabakh, South Ossetia...

Come to think of it, would you care to mention the most recent occasion when we in England engaged in the exclusion of alternate ways of life within our specific geographic territory? I can't think of anything much more recent than 1290, but maybe you can enlighten me.
