That’s pretty much it. If you visit somewhere like r/CasualUK you will get people talking about “up north” and “being a proud northerner” and such like. They are all English people talking about England. Which is fine, but it’s supposed to be a UK subreddit.
Even when foreigners are asking about travel advice. Must confuse the hell out of them. Or maybe some foreigners think that England = UK anyway so it all balances out?
