I'm Brazilian so I know what I'm talking about when I tell you how divided the country is about this, it's not a matter of " nice subjective thoughts" or finding excuses to push a narrative, it's just how things are. The close election results reflect that, it was 51% vs. 49% for Lula.

Generally speaking, the southern states are predominantly pro Bolsonaro and the northeastern states are predominantly pro Lula. Everything else in between is a toss up, it really depends on the people you talked to, which by no means can represent the overall opinion of the Brazilian population.

Edit: also the richer and whiter the brazilians, the bigger the chances of them being a Bolsonaro supporter.

Depending on the places you went to, that could be like saying you've been in 3 different cities in Texas and got shocked when you heard how much people would rather have Trump instead of Biden.
