Yeah, but thankfully most I've seen were more about showing it off on a higher level and having a bigger event than having a "winner" and a "loser." Once they start handing out precious metal medals, trophies and belts though, they've already forgotten why the art was developed in the first place and have become the coloniser. Apparently there's even going to be a "world championship" in Curitiba of all places. (For the foreigners, the South is skin cancer crackerland in Brazil, with some of them even wanting to separate from the country)
