A bodybuilder have chosen the ultimate intense physical and psychological challenging path, going for no less than perfection.
Yet their chosen activity is peaceful and doesn't aim to inflict any harm to fellow competitors.
Compare that to most other sports, and especially pro MMA.
Instead of projecting the concept of physical violence on to the world, the bodybuilder have chosen to project triumph of artistic willpower
And they use their discipline to avoid violence instead of causing it! And to be friendly and help other that engage in the same activity.
We must put MMA and bodybuilding in their right perspective.
That's why a true master, even an mixed martial arts master!, would never engage in UFC fighting, and alike.
Now we must be fair and certainly come down hard on MMA, more than bodybuilding, at least.
