@georgeob1,
Your references to the past are certainly correct. (And they will be correct in 10, 100, 1.000 and 10.000 years.)
But times have changed since then. Humans, and society, too.
(Britain got some immigration waves from the Irish (millions of residents in the UK) and Scots (Dál Riatan Scots as the earliest) as well.)
And since you mentioned "Jonathan Swift, himself a low level COE (I) cleric", I just want to remind at the "Red Vicar of Thaxted", Conrad le Despenser Roden Noel, a prominent British Christian Socialist. [Thaxted is a lovely town, as an aside.]
