I think it’s negative. While MMA is more about kicking the other person’s ass martial arts such as Tae Kwon Do are more about defending yourself.
Positive or Negative for who?
And what criteria do we judge MMA for Kids?
Since I have no children I know of, I can’t say for sure how I’d feel if it would be my child paraticipating in MMA.
Still, even as stupid ideas go, this may actually have some benefit.
Exposing children to violence and getting them used to both being attacked by, and attacking, others probably has a tremendous effect.
Trying to provide a violence free exsistence is very difficult and those who are not used to being violent themselves are probably at a great disadvantage.
