In that case, I'll go back to the question you posed in your previous post:
My answer to that would be "Brexit".
Because let's be honest, to those living in areas not heavily affected by the influx of Polish and other East Europeans, but who still voted Brexit because of concerns about immigration, did so because, let's face it, to them immigration is all about those from outside Europe (and outside the 'white' Commonwealth).
And that in turn is heavily influenced by the perception (real or otherwise) that many of those with roots from places like Pakistan see themselves as not part of British society, as being separate from it, and wish to keep it that way whilst enjoying all the benefits and privileges of being British citizens.
In fact, your own post has hinted at something along similar lines:
So yes, it does matter how one is perceived by the rest of (British) society.
I don't accept this post at all.
Brexit in the North came as a result of lots of factors, none of them to do with fifty and sixty year old West Indian and Asian immigration.
And I was one of those northern Brexit voters, albeit more educated than most.
Firstly, there was Thatcher's de-industrialisation which took away our employment base.
Secondly, there was her war on mining communities.
(Try to remember at this point that I'm actually a Tory, not a militant leftie).
Huge swathes of England and Wales now have no jobs except poorly paid service ones and trades.
And now highly educated Eastern Europeans come in and do those jobs for tiny wages.
Brexit was about that.
