Well, if you read enough history of BJJ this attitude was very common among Brazilians during its time. The BJJ schools (and Lutre Liva) liked to go out and fight and thus the stereotype. I don't think its like boxing in America because there isn't an attitude that these boxers are going out and getting into fights with each other or picking fights. I should have added the details that I had already heard this reputation prior to speaking with the student and it did reinforce that perception. For reference, here is a forum discussing this very thing about it in Brazil back in 2013, so it wasn't just me hearing one person's opinion it was based on hearing and reading the same thing over and over. I trained a limited time in BJJ and have friends that have been at it a very long time and have heard the samething through training in it as well. Is BJJ Really That Big A Deal, in Brazil?
