I don't mind it being brutal one bit. The problem is it is not voluntary. As such, it approaches the level of torture in my eyes.
The children are selected at young ages to go to sports schools
those with the most potential... the kids... are given far too much choice and freedom. As a whole they dont begin to understand sacrifice and dedication, and even worse, those so very rare few who do are ridiculed and attacked for it.
It is true that we don't know the exact level of coercion being used on the children, but I think its naive to think there is none.
