I believe most people would say that the more 'manly sport' would be rugby, which is a harsh game with a great chance of injury. The idea about this though is what makes a sport manly? I believe that all sports pose a certain degree of 'manliness' and it all depends on how you look at it. Is it considered manly to engage in a sport that although entertaining and fun is dangerous? Or would it be more manly to protect yourself and your body and yet still have a fairly brutal game with just as much entertainment? It all depends on how you look at it. I greatly enjoy both games but do not consider either of them 'manly.' I am a girl and I enjoy playing both games as well (although not in the extremes but just for the aspects of the sport). If you believe one sport is manly over the other I have a tendency to believe you are laying down the stereotype of man and especially now days there should be no extreme stereotypes!
