The popularity of 'violence' in movies is a compensatory response to a certain neutering of males that our secular word engenders, driving out vigor, testosterone, maleness.

Go to a gym today and you'll see signs:  "No grunting"  "No tank tops".  "Don't drop the weights". 

In the media it happens too.  

NCR, for instance, suppressed any articles on Memorial Day (heroism, 99% male) as well as Father's Day.  Not a single article on either of these two topics. 

It's why young Iraqi males gravitate to insurgent activities.  Saddaam "rooted out" true "machismo" action among the males population (machismo in the best, traditional, original sense of the term > a strong worker standing up to bad boss behavior among the laboring class).

I shared billeting space with "Graham" a CIA field agent in Iraq.  He explained the whole sorry story.  

And I saw the effeminancy in our Iraq military counterparts. Soft.

Our society is rather flabby and flaccid.  Men become something other than men.
