Seems like, teaching our sons that there are many more emotions than anger...would help.
Exactly! That's why it's sooo important for fathers to actually have a relationship with their sons. To talk it out with them, good or bad, whatever "it" happens to be. There are age appropriate ways of dealing with nearly every issue that comes up in a family setting not to mention the many incidences of regular life outside the home.
