I would say that it's all about emasculating men in the US, but I know some of these people and it's deeper than that. They do not feel the players are intelligent enough to decide for themselves if the risk is worth it. The idea of personal responsibility, individuality, and personal decisions does not even cross their minds. "They" know better, and "they" will fix it by taking the decision away. It's all about expanding the government's power. The fact that it reduces or takes away a traditionally "male" activity is just a fringe bonus that makes the world "more civilized" in their opinion.
