I'm not sure how my comment was interpreted as "it's impossible to be wrong". I made a narrow claim that faking English knowledge in Brazil and Portugal is harder today than in the 19th century.
It is, relative to the 19th century. It is much easier for anyone with internet access to immerse themselves in English language media.
I know specifically that English skills are far from universal in the Portuguese speaking world. But it's way easier and more common than even 30 years ago. So are you really saying it's the same as the 1870s? Please.
