It was largely Amerindians who were exterminated and genocided with ease.
Conquering empires that were near-peers technologically is different from settling a continent which was at the losing end of the Colombian exchange.
edit: we are just comparing 2 completely different models here. You're not wrong about some things, you are just talking about a different thing than I :)
edit 2: you are lacking information if you think that Brazilian Amerindians did not also partner with European powers (France and the NL itself comes to mind) against the Portuguese and it's somewhat amusing that you think that Portugal was never challenged on that vast territory by other powers.
Subjugating a native people that lacked metalworking, gunpowder, and literacy is different from conquering multiple nations that had all of those and was backed by the Ottomans, Mughals, and Americans.
Heck, the only reason the Dutch couldn't completely invade Aceh was because the Ottomans and Mughals threatened to sanction the Dutch [2] in the 17th century for threatening a fellow Sunni state.
We are reverting to the historical norm where we don't need you Farangis anymore. O facto de o IDH da Malásia ter atingido o IDH de Portugal de há 7 anos mostra que vocês, portugueses, precisam de rever os vossos egos. Tendo passado anos em Boston, conheci muitas pessoas do seu tipo - Brasileiro e português.
