I had a look at this video from a purportedly White Brazilian speaking with an American Dissident-Right content creator who has been around for a while.

A few things here might be of interest to you.

16:38: I didn't realize that the usual gang/Cartel types up north were that partisan. I knew that they'd benefit from a Lula victory and that they hated Bolsonaro because he was harsher on them... but not that they saw Lula as their man or something like that. In this clip, you have these brown retards, allegedly in Rio, literally firing their automatic weapons in the air, purportedly in celebration of his victory.

21:55: I've been seeing other videos in which purported Bolsonaro supporters were shot dead, but I wasn't too sure, since the amount of violent videos coming from there is insane. I'm now fully convinced that the Cartel types really are killing people over their beliefs, though. The guest goes on to claim that even the criminals in prison are celebrating.

29:33: There are actually many NatSoc types in southern Brazil?
