I would just like to point out that unless you can trace your ancestry back to the ancient Britons or Celts before the romans conquered the south of britain we are all immigrants not that I condone people who have not contributed to the country in taxes getting benefits and housing just by turning up at the claimants entrance.
Really depends on if you start drawing history lines for convenience. Ancient humans are thought to originate in Africa, so in a sense,
everyone elsewhere is an immigrant. Not sure I altogether buy that, but no one really knows, and if we did, would it matter?
As far as I know, the later Anglo? / Celt split wasn't a "racial" thing, just about territory, though still used politically to create artificial division.
The Romans, Saxons, and Normans, came with force, to a lesser extent so did the Vikings (by this time "racial" groups had names).
The difference this time is that it's by infiltration, aided by commerce and a self centered political class. Immigration has some benefits,
but it has to be done at a pace broadly acceptable, and the net worth realistically and honestly assessed.
In simplest terms, we should get to choose our own "friends" as a country, just as we do as individuals.
And we already have too many people, how is more a good thing, under any pretext ?
