Forced physical altercation on 12 year old, about to whoop my dad's a$$

My father, mother, martial arts instructor are forcing my 12 year old brother to fight in a heavyweight division (240lbs+) kickboxing match in a 19+ or older male division unsanctioned tournament (multiple fights within a few hours). The incentive and benefits: to teach a 12 year old to be brave. The risks are more obvious here. All the authority figures in my brothers life all unanimously agreed to send him to his first amateur fight in the heavyweight division at the age of 12 years old. He is 5'4, morbidly obese, and far from a professional fighter.When news first struck my brother, he started bawling his eyes. My parent's response? They took all of his possessions away and forced him for two options: fight or get angry at the instructor (tell him to f* off). So because the martial arts instructor decided to force my brother to fight in a heavyweight amateur kickboxing match, my parents agreed to take away all of my brothers possessions and force him into this tournament.There have been events like this in the past: my brother was forced in a street fight with other boys in the class where he went home and had a broken nose and multiple contusions on his face. This happened on more than one occasion.My dad is the biggest b!tch in the world. I am pretty close to whooping his ass in my own home version of a kickboxing match. He states that it is fine that the people my brother will be [FIGHTING] is 3 times taller and bigger, trained fighters that will most likely murder him. This is all in the good name of "participation teaches you to be brave".So please, if someone has half decent advice, let me know. All troll responses will be flagged, reported, and deleted. I am pretty close to knocking all my dad's teeth out and telling him the same thing he told my brother and I (when I was a young kid), so please, in the name of mercy, someone tell me some decent advice here. via /r/Parenting http://bit.ly/2W2D70D
