Men throughout history have always been required to make sacrifices in order to ensure the good of the species and the security of their loved ones. I believe that this is to be respected and honoured. However, I do not believe that we retain the right, in an age when survival is essentially assured, to demand that Men continue to make such sacrifices.
Ultimately, the power to sacrifice makes Men capable of accomplishing incredible feats, and when he has some purpose that is worthy of sacrifice; it makes him happier, healthier, stronger, and wiser. But if he wishes to tap that incredible power source, it must be on his terms.
