As the person who regularly cleans up threads, some of them are legitimately different (the spanish-speaking world is pretty diverse), some not so much.
However, I’d like to note that you are in full control of what categories you see on the latest page, notifications, and emails. Visit any category page (ex. Español), click the button in the top right-hand corner and choose to Mute the entire category. You won’t be bothered by it ever again.
