To the first one, he literally has gotten death threats from Brazilian fans telling him that if he ever were to attend an event in Brazil, so I'd understand why he wouldn't want to go there.
Second one, I don't know what's bad at that, Rio does have a gigantic problem with gang criminality, especially in Slums, and telling pro's that are behaving like ones that they are no gangster's,what's the problem?
third one is literally true, Brazilian fans are one of the most annoying ones(not the majority, but the outspoken minority) and he makes a joke about it.
Fourth one refers to the many death threats he has gotten by Brazilian fans
Fifth one critizises KNG, who literally threatened someone to kill him, and refers back to the Crime problem in Brazil, so it would be unsafe to hold a major there.
Sixth one admittedly was bad taste, but it was a joke in the end, albeit a racist one. I found it a bit too harsh, but the best jokes are the ones that are offensive
Seventh one, again, critizises the behaviour of Brazilian fans.
Last one is about a Vietnamese guy, nothing to do with Brazil.
So to summarize, most of the stuff either is directed against Brazilian fans that behave badly, or critizises Brazil as a place with high crime rates. I know you think that he is a racist,and I certainly think he said some racist stuff, but I doubt he truly is racist, but rather a guy making edgy jokes that sometimes go a bit over the top.
