I think it’s because of the size difference in the fan base. Nobody in the USA, for instance, gets in fights because of futbol, but football rivalries have caused death. Heck, one of my coworkers saw a man get castrated because of a college rivalry on game day. The difference? Fan base in USA is very small for futbol, very large for football. A larger fanbase means that the long tail of the distribution curve is more likely to pop up.
