There's no fighting allowed in football, baseball, soccer, or basketball. Hockey's the only major sport where you can get away with it, and not be kicked out automatically. So clearly, the NHL people know that fighting is what fans want, and it keeps them coming. And to their credit, the NHL doesn't pretend that they want to completely remove fighting.
So then, why does the IFBB "mark down" synthol users instead of just ejecting them completely, since they claim they want to remove the scourge from the sport? Considering bodybuilding is about muscle, why isn't sporting fake muscle the gravest of offenses?
