In general, most people in Europe can distinguish between governments and citizens. Sure, governments are elected and reflect public opinion to some extent; that’s true. But people also recognise that individuals may or may not agree with their government, so there’s usually a bit of benefit of the doubt from the start.
From what I’ve seen, people who travel tend to be more respectful and a bit more low-key, too. You might have strong opinions about one leader or another, but when you’re abroad, you don’t usually wave that flag around. It makes it easier to connect with locals, wherever you are.
That said, if you show up with that loud, arrogant, entitled and ignorant attitude typical of "that" group -we all know who we're talking about, right?-… don’t be surprised if people tell you to get lost, or things get a bit tense.
And don’t try to hide where you’re from, you can’t. In places like mine, which have been receiving visitors from all over the world for decades, people can usually tell where you’re from a mile away. There’s no need to hide anything anyway if you show up with respect and no intention of picking a fight.
I’d say that’s pretty much the vibe around here, now and always.
Also, and not trying to sound rude, but if you’re visiting a big city, most people really don’t care who you are, where you’re from, or what you think. The vast majority aren’t connected to the tourism industry, so to them, you’re more of a nuisance than anything else. It’s not personal, it’s just what mass tourism does. You see it in Barcelona, but also in Paris, London, or Rome.
