" comparing UK and 2016 Brexit vote, with Weimar Republic and their 1933 vote. "
A bit extreme definitely, I was a very determined remainer from 2016-2020 (now I'm brexit-agnostic, it's bad but nowehere near as bad as I feared and the EU is in a mess now anyway which we might yet be glad not to be inside), and whilst I expected many terribe things to come of it Nazi style rule wasn't one of them. The snoopers charter of 2016, and the lockdowns of 2020, were much more like voting in Hitler than brexit was. In the aftermath of brexit I expected we'd lose a lot of our fundamental rights due to the UK sneaking away from the EU human rights courts, but then those human rights courts spent 2020 proving they no longer cared about human rights (while the Uk was still in), and the EU now is becoming increasingly tyranical itself with plans for digital IDs and for mass scale internet censorship*. Brexit wasn't the biggest problem, all the other things which went on while brexit had people distracted were. Today ofcourse, the political class use immigration as as a distraction, to keeppeople's attention while truly dangerous things with CBDC plans are done in the background. Also, since Britain has been out of the EU, it has actually morphed a lot more in to the bad things (unified EU vaccine digital ID passes, EU digital services diktats, EU plans for close collaboration wih the disgraced WHO, EU plans to spy on journalists...) which brexiteers claimed (incorrectly at THAT time) it was in 2016.
*just the same asmost of the rest of the world, virtually everywhere is in need of a regime change in which the bureaucratic authoritarian busy-body jobsworth tick-box class all get kicked out of politics and sent in to eternal unemployment where they can do no further harm
