I spent a long time rebutting each counterfactual in turn, but then I recognised that I was falling for a gish gallop. Furthermore, as dang is (rightly) adamant about avoiding personal remarks, I had to cut out the funny bits.
So instead, here's the simple truth.
The UK, in a surge of authoritarianism, cut its own balls off by leaving the EU (and the Civil rights it confers). It did this to appease fringe nutjobs and to make a pile of money for hedgies. Then it howled in pain and blamed the EU, even though the EU was against the chopping of the plums from the get-go.
The conditions for this bollockectomy were created by a barely-elected government, after the fall of which we have had, mainly, unelected government.
This entire manoeuvre was done under a screed of fractal dishonesty, in which scuttling little fibs decorate a structure of brassy falsehoods all stacked higgledy-piggledy on a giant whopper. Unwilling to accept the blame, the responsible parties continue to lie to this day.
In a parallel move completely unrelated to the above, the unelected UK government is ramping up surveillance. The EU has not done this, but the liars blame it anyway.
