Seattle WA: Professional Soccer is now being played in this city. "The Spoof" being basically a British (don't see any French do you) publication, it is a rather delicate matter to rationally discuss Soccer verses American Football. Both Soccer and American Football can be exciting and both employ superbly qualified athletes.
However, the question must be forthrightly addressed; is Soccer more passionate than American Football? A qualified yes to passionate, but not on the Soccer field, only in the stands or before and after the "match" is over.
Soccer fans have been known to riot in the stands when the other team scores a goal, assuming the stands don't collapse first. A barricade may be erected to separate rival fans from engaging in brawls or fistfights. (Other sedate fans flee in panic.) Then there is the occasional murder or the burning of a defenseless automobile on the way home from the "match".
There is some historical evidence to support Soccer "hooliganism" in earlier historical periods. Are these currently described unruly Soccer events overblown in the press? Americans also sometimes get over exuberant when a Basketball or Baseball Championship is won! There is no recorded incidence of "kill the Umpire" ever being carried out. A real question to be answered; now that Soccer has arrived in the USA is off the field Soccer violence here too?"
