Maybe not, but lets not split hairs here. The op was discussing comparing nations and used a blanket "EU" moniker to denote this. You know, our next door neighbours of similar economic size...
And yes, this distinction is important. The british people have democratically decided to leave the EU.
With that out of the way, you should read "EU" as being in parentheses.
What a nice excuse. I dont buy it. No decision is ever made by "the people", every poll will end up being discussed in some parliament, and politicians will have the final say.
But the british people voted to exit, and that is what happened. I really dont know why supporters of democracy have any problem with that.
