A very rambling speech, the Brazil part barely is heard (I had to watch it twice to hear it well), but it's a perfect example of a political speech where he talks a lot and says nothing.
He’s basically saying Argentina is a white country (Boats = European colonizers) in order to kiss Spanish ass since this is an Argentina-Spain relations kind of event, acting like Argentina is some sort of their direct descendant more than like, Mexico because there it has more darker looking people.
And he also compares it to other Latin American countries (Mexicans came from Indians = Indigenous; Brazilians came from Jungle = Africans) in order to reinforce Argentina’s European-ness lol. As if most Argentinians didn’t have some Indigenous inheritance like in other countries, or as if people from other places could be reduced to one single origin instead of mixed backgrounds from all over the place.
It’s basically the countryball meme coming into life.
The worst thing is that it allowed a racist like Bolsonaro to act like he celebrates diversity in his country (we all know he doesn’t), use minorities image for self-promotion after contributing for their erasure and mock the left-wing Argentinian president as the real racist.
