yeah it just looks more intense because instead of some people really like the american football and other people being into the basketball, everyone is just a massive group of footbal fans (although like brazilians do enjoy sports in general it is just that footbal and the national team in particular is a part of the brazilian identity, like even to people who are not big football fans on a normal time might become hardcore supporters, and it is also why the effect of the 7x1 defeat to germany at home was actual trauma to the brazilian collective mind, that was our 9/11) like this was the reception flamengo got from getting one of their libertadores's cup wins and this seems pretty on par with a superbowl win reception for example
