How can we expect to have well-rounded men when family and society sabotage them as boys?

There are numerous factors sabotaging boys from the time they can speak. Boys are made to believe they are suppose to “man up” and not cry or get sad over stuff. If it is not coming from parents, it is coming from the media. If a man and his son was in a boat and big wave crashed the vessel nearly swamping it, if the father was afraid, he would never admit it to his son, he would ask the boy “that was a huge wave, you were not scared at all, were you?”, instead of allowing the boy to be scared. If his dog gets hit by a car or has to be put to sleep because of a run in with a bear camping, the boy would not be allowed to wail and mourn the dog, at least not more than 2 hours. There are many more ways in which boys can’t be boys because people tell them to be boys people believe they should be. If they can’t be the boys nature would have them but forcefully molded into the boy society and family believes he should be, how can he possibly grow into a well-rounded man?
