"
I can't imagine how -any- Welsh, Irish or Scots could support any "liberal/PC/multicultural" views."
They likely don't! The way it works is the citizens work hard and are highly taxed. So highly taxed that having children isn't a logical choice.
The immigrants arrive and get all sorts of welfare support and multiply like roaches.
Most northeastern Irish (Boston, for example) overwhelmingly vote Democrat.
This tends to be directly opposite to the Welsh/Scots/Irish blooded people who inhabit the Appalachians. [my area]
