The fact that the native population of Britain changed repeatedly thousands of years ago doesn't seem very relevant either. Are you saying that if new evidence showed that the native populations of America or Australia were the result of multiple ancient waves of migration rather than just one, that would change anyone's mind on which ones are truly the native Americans or Australians? That's obviously absurd.
If you really want to turn this apparently simple discussion about the common meaning of words into a matter of first-principles definitions, I guess I could give it a try, and it would probably have to bring in things like whether the waves of migration retained a significant identification with their place of origin. But it seems totally unnecessary.
Not if they were truly ancient because they would still all have been there tens of thousands of years.
If you can find a still distinct pre-Columbian group who migrated to the Americas in the last millennium or two I would agree they are not an indigenous population.
> The fact that the native population of Britain changed repeatedly thousands of years ago
Not changed repeatedly thousands of years ago. kept changing repeatedly all the last few thousand years. Britsh history simply makes it impossible to come up with a sensible definition of indigenous, so any definition of native has to be very different from the American one, and will be a lot less clear cut and impossible to reach a consensus on. I would expect quite a few Welsh people to argue that the English are not indigenous.
One of the British politicians who DHH likes quoted stats about the number of people in the country who are not ethnically white British. The definition he used classifies people like the King and Winston Churchill as not British. He became very evasive when ashed about this in an interview https://www.telegraph.co.uk/news/2026/08/07/rupert-lowe-rest...
That's not really what the argument is about, it's about whether such a group would invalidate the concept of "native American" entirely such that it wouldn't be meaningful to distinguish between the native Americans or the non-native European Americans. That's effectively what you're arguing for Britain, and it's absurd.
>Britsh history simply makes it impossible to come up with a sensible definition of indigenous
Taking the example of the Normans that you mentioned somewhere else in the thread, what's the difference between them and your hypothetical pre-Columbian group? Why does the Normans make it impossible to come up with a sensible definition of indigenous when another migration wave arrives, while the hypothetical pre-Columbians don't?
Suppose groups that had reached the Americas before Columbus, such as the Norse, probably Polynesians, possibly others, had settled in large numbers instead of just a fleeting contact, and that had happened repeatedly since the first peopling of the Americas, and some of the groups had merged with earlier groups, and some had not, then how would you define a native American?
This is exactly what you have in the UK. I notice you have ignored my comment asking you to provide a clear definition of native British. Given that most saves of immigration to the UK have merged into existing populations do specify how much of people's ancestry needs to be whatever you call "native" for it to count.
In the context of the wave of post-1492 European migration to America, I would define it to mean as anyone who isn't coming from that specific migration wave. It would remain easy, so long as the specific migration wave is still easy to distinguish from the the others.
You're now saying explicitly that if some new archeological evidence showed multiple waves of Polynesians in large numbers, then you would suddenly have trouble defining the distinction between a native American and an European in the post-1492 context, but this still seems completely absurd to me. So I'm afraid I don't really know what you're talking about.
The point that I was making is that this is the "definition" I would use for Britain as well, when discussing a very specific phenomenon of modern migration into Britain. Anyone who was there before the modern wave counts as native. As with all attempted formal definitions of real world phenomena, you can keep digging at and asking whether e.g. the Polish or Irish waves of immigration are distinct from the "current" ones that people are talking about. But there shouldn't be any doubts about the Normans 1000 years ago any more than there would be about the hypothetical Polynesians.
You are trying to a complex reality into as a simplistic (American?) world view.
Also, its normal to use quotation marks when quoting someone.
What do you mean by "built"? What would someone have to do to qualify? To when do you place the start of the "jet age"? What do you man by "someone"? No one born in the last 70 years built anything before the jet age. If you mean their ancestors, what proportion of their ancestors?
So up to the mid 20th century? Completely arbitrary. Why not by the start of the 20th century, or the start of the 19th century, or after the Norman conquest, or the people who were native to the country at the time of the the Roman invasion?
