I have just one question about the latest shooting in Maryland. What violent video games was this American playing?

Nearly all of the murderers in these circumstances have a violent game they play that dehumanizes their killing. 

In isolation these games appear to have no effect on the view of young adults about society. However, where that young person has the opportunity to carry out the violence while suffering from self-hatred, these games facilitate their actions. 

They are also sexualized from the point of view, young men tend to act in violent ways more often than do young women. As a rule these games are played by men and not women. These games tap right into the definition of  masculinity in the USA. I mean they aren't handing out flowers to folks, now are they? They don't attempt diplomacy in a suit at a table of strategic language and contract. This is about the masculinity of guns and a superior meaning of their use. 

These games don't portray that guns are misused in our society at all. 

Then enter stage right Smith and Wesson objecting to microstamping and one has to wonder how many guns are actually used for the purpose of self-defense and sport in the USA. Sports hunting is on the decline, but, the sale of guns are astronomical to that reality. 

"Life is an opportunity, benefit from it.
Life is beauty, admire it.
Life is a dream, realize it.
Life is a challenge, meet it.
Life is a duty, complete it.
Life is a game, play it.
Life is a promise, fulfill it.
Life is sorrow, overcome it.
Life is a song, sing it.
Life is a struggle, accept it.

Life is a tragedy, confront it.
Life is an adventure, dare it.
Life is luck, make it.
Life is life, fight for it."
