Those people who assert to ban dangerous sport in publics, the first thing they have to do is to define what sorts of sports are dangerous. Clearly, people divide the sport according to their tendency to lead people injury. But dilemma has occurred here. We all know that there is no definite safe or dangerous sports. Even the safest sports , you can name it, be it running or swimming, they all can induce danger or even pose a threat to people's life. Sport player may involve in incidents or they can be drowned, this is not limited to those who are unable to swimming, but also evident among those who are good at swimming, they may die because of exhaustion or careless or even be attacked by shark when they swimming in sea. So, the so called safe sports do take people's lives.
Opposing, if in a extreme sport such as skiing, if the player have been correctly educated and trained, with proper protective equipment and play with cautions, then the danger will minimize to the least, even safer than the so called safe sports.
To sum up, there is not really dangerous sports if we have put necessary protective equipment, or the proper training and the education has been set in. meanwhile, even the non-dangerous sport also brings bad results if we are careless. So, probably, no sport is really dangerous, the real danger is careless and unsecure equipment. Thus, governments’ role here is not to ban the dangerous sport, but to provide the proper guide to let the player enjoy the sport and in the mean time knows how to play
