Are 'real' men a dying species?

Afer sitting down and reading 'Stories to turn boys into men' and after having one of my insomniac nights were i just lie back and think until the morning. I realised the book brang up many good points. Modern man has changed in the last 50 years quite significantly. A man in the past would be raised to respect others, to earn others respect, put yourself before others and work harder to help others as well as being a brave and determined to accomplish the challenges at hand. These qualities created men such as the Spartans at Thermopylae, Julius Ceasar, Salahudin, Martin Luther King, Ned Kelly, William Wallace, Ghandi, Galileo are only a few more famous examples. I'm not saying that all men have lost these qualities, but fewer and fewer are being found. Boys are brought up these days to strive for their own success, to push competitors out of the way, to do what ever they want as long as their not to . This leads to men who if needed in a struggle would only walk away, concerned that he might ruin his new shoes or strain his back. I myself am not a 'real' man, I've spent my life trying to be better than everyone else, the only times I helped people was so that I would receive some sort of approval or benefit and unless my direct family or myself was placed in harms way, I would only try to ignore the problem. Not all men have become like this, it's just sad that fewer and fewer heroes are showing up and so it only makes me more determined to teach my son the qualities every boy should be taught to become a great man. So, do you agree, are 'real' men a dying out?
