No different than America promoting football for young kids. Many kids had brain concussion or broken bones or worst, paralyzed. This is ONE unfortunate fight that took this young man's life.
same thing as playing full contact football in peewee leagues...kids are going to get hurt and injured regardless.
The main difference is it's more of a 'want' here and more of a 'need' over there...And there are more regs to protect the participants here i.e., mandatory headgear, shorter rounds, etc...in regards to combat sports...
Though not immune to all injuries like pretty much every activity in life, at least there are some guidelines for youth participants protection here ...If it still doesn't do enough, and they could change it or ban that particular combat sport...
