It's kind of hard to revolt and take up arms against your political masters when you've allowed the masters to take your arms. I wonder how the British "SUBJECTS" like living in the liberal wet dream of complete control of their lives?
The UK is, however, rapidly becoming less stable year on year, courtesy of vast overimmigration, equally vast underassimilation, and rigidly enforced multiculturalism at the council level. Sort of a mini-Balkanisation, if you like. This tendency is not only not going to reverse itself, but will in fact accelerate in years to come.
The social fabric is irreparably torn, and in about a decade's time, maybe less, one good hard push, presumably an exogenous one (but who knows, eh?), and you'll see some flavour of serious civil unrest in that island.
Conceivably even a full-blown revolution is a plausible occurrence, although I consider it very unlikely right this minute. Doubtless our British colleagues here will have several thoughts on this topic.
