They did a mess in Brazil too. Extracted what they could, be it wood or gold and everything in between. Gold in particular was a pretty good shakedown. We learned about all the B.S. at school.
I am Brazilian. I do not blame the current Portuguese people. Heck, I don't even blame the Portuguese back then, just their government. I want Portugal to prosper.
Asking for an official apology is fine. Blaming ordinary people who are just trying to live their lives, is not fine.
