I will try to explain as impartially as possible.
Rivalry between Brazil and other South American countries has existed for a long time due to football, cultural differences, etc.
It's a combination that would certainly go wrong most of the time, Brazilians who have the above temperament sometimes and we tend to defend our country a lot when foreigners talk about it, and the MANITOS who have a good history of acid provocation, often racist, just researching recent cases of Argentine fans imitating monkeys for the stands of Brazilian soccer teams, this year alone there were many. (I'm not saying that BR doesn't have it, I'm just contextualizing it).
Then we get to the games, the BR community has always been very engaged in Couter Strike, and there, we often share servers with Argentines and etc, unlike Valorant. And on these CS servers, MANY TIMES the Argentines were on one side cursing us as a monkey and on the other we were cursing them back as BOLUDOS.
Then we arrive at Valorant, Keznit makes references in some situations imitating monkey playing with Brazilians, some say it's out of context, then again associates DGZIN with CJ, obviously, for all this history, many Brazilians would find this behavior strange, how it happened. And since racism is a much discussed issue here in Brazil, anyone who really thinks keznit is racist wants his head, and they won't give up until he's screwed.
This site shouldn't be a parameter to discuss this kind of thing because there are a lot of baiter and children who want to show up, or just weirdos who live 24 hours a day in internet forums and just want to talk bad about BR at the first opportunity they have. So any attempt at dialogue that exists will be ruined by this type of person.
I hope that was clear, my point of view, obviously.
