Well, it's made easier when you get people naming names of who the sovereignty is being ceded to. It's one thing to say "loss of sovereignty" and another to then go on to talk about who it's being ceded to. It's often not even correct.
> Mostly, massive immigration that overloaded public services.
Except it was per-capita underfunding that caused public services to be underfunded. Almost every study done on this found that EU migrants were on above-average wages and hence paying more tax. And if there weren't, there were measures that could have been implemented such as asking people under free movement rules to demonstrate their ability to support themselves and not be a burden to the state. Other EU states do this.
Most public services should decrease in cost per person as it scales up. If it's super-linear there's something seriously wrong with the way you deliver public services. So it was the underfunding per-capita of public services that was the problem. Instead of expanding public services, the coalition government cut them drastically whilst outsourcing everything they could.
> In response they were told, sorry, we can't do anything about that, France and Germany won't let us. It's out of the question, even trying to talk about it is pointless. Oh yeah, and you're probably a racist for even asking.
We heard a lot that it "was not racist to be concerned about immigration." And a good proportion of people who agreed with that were in fact racist. Let's be honest, a lot of people in this country are prejudiced against people based on their ethnicity, which is pretty much textbook racist. I've even heard on the doorstep that "it's alright to hate polish people because they're white." Attitudes like "they shouldn't be here" are quite common and seem to be more openly voiced after the referendum. It's certainly ignorant of history if you believe that immigration is a recent thing as many who espouse these attitudes seem to do. Go back a few of hundred years and you wouldn't have known if somebody was from the North or France. Both would be just as incomprehensible.
> Ultimately technological progress does allow us to satisfactorily decentralise power in new ways. Some people want society to go in the opposite direction and centralise it as much as possible. This is a bad idea, and the Eurozone predicament is an interesting example of why.
The Eurozone predicament is complicated. There are merits and demerits to centralisation. We should all be wary of extrapolating problems with one large system to all large systems.
