Ah I think I understand. I definitely think the point is worth making that England seems to be one of the only places on earth that doesn't value - or even recognise the existence of - its own native population, even as a point of debate. It's definitely nothing to do with segregation, which is just something else.

No one in most countries would argue that their native population doesn't exist as a category. In fact while in the US the native Americans have been treated very badly in the past, that hopefully doesn't happen too much today, and they are quite honoured in some ways.
