A parable?

Let's suppose, for example, that ethnic Asians, having fled to Britain to escape 
persecution in Uganda, have prospered and become a 33% minority of some un-
named British county.  Suppose further that they have established businesses and 
farms and have purchased some 7% of the property in the county.

Suppose still further that a minority of the British natives have occasionally mounted 
racist attacks and have even fire-bombed some Ugandans' homes and businesses, and 
sadly, some Ugandans have responded in kind.  This might result in a proposal to 
partition the county by devising a boundary surrounding an area in which the 
Ugandans constitute a 55% majority, and leaving them to form their own independent 
administration within that area according to their own traditions and laws, but with 
complete protection for the rights of the 45% non-Ugandan minority.  It would also be 
expected that goods and people would be ensured free passage and trade between the 
partitioned area and the rest of the county, and the opportunity to migrate, but only for 
Ugandans inward and British outward.

Of course, there might be some irrational resistance to such an idea by the native 
British, and even though such proposals are made in good faith and with the intent of 
stopping inter-cultural conflict, it might be felt by the Ugandans that their boundaries 
are not easily defended, and they might seek to expand them to more defensible ones.  
Of course, there might be irrational resistance to such moves, and conflict might 
erupt, even violence.  The Ugandans might in this case seek the support of other 
nations harbouring fellow Ugandans, and if the fighting became heavy, many of the 
British natives might flee the area, perhaps expecting to return when conflict ends....

Suppose the Ugandans were successful in defending the increased area and preventing 
the return of the natives, and decided to encourage Ugandan exiles living in other 
counties to join them and occupy the 'abandoned' British properties, thus achieving a 
considerable numeric majority in the expanded area. The counties which formerly 
hosted the new arrivals would probably be glad to see them leave, due to resentment 
within their own native resident populations at the treatment of the British natives by 
the Ugandans...

Now constituting a clear majority, well-armed and holding the area securely, and with 
powerful foreign allies, the Ugandan State declares it has "a right to exist".
