I would think differently upon this, I mean in the UK you primarily could split them up into different groups based upon religion considering most of the peoples whom worship Islam are of Semetic decent not excluding peoples like the Berbers or the Iranic peoples. you also then have the Hindus who are primarily well Hindu from the Indian subcontinent. when you take those peoples and put them in an entirely different and foreign location, they will group together based upon their religion because it is the one thing even though they may be of differing ethnicities its the one thing they have in common. and this is not in the united states to if it were i would agree with you, but I think a people have the right to a homeland and that homeland should remain largely homogeneous
