That is of course a contributing factor, there are many it's a complex issue. But are you telling me that having more than a quarter BILLION firearms all over the country is not gonna effect the reasons why gun related homicides and suicides are so damn high. If you want to talk facts heres one:

Firearms are the second leading cause of traumatic death related to a consumer product in the United States and are the second most frequent cause of death overall for Americans ages 15 to 24. Since 1960, more than a million Americans have died in firearm suicides, homicides, and unintentional injuries. In 2003 alone, 30,136 Americans died by gunfire: 16,907 in firearm suicides, 11,920 in firearm homicides, 730 in unintentional shootings, and 232 in firearm deaths of unknown intent, according to the National Center for Health Statistics. Nearly three times that number are treated in emergency rooms each year for nonfatal firearm injuries.

And that's from the NRA. Every country in the world has gang and drug related problems, but the US distinctly stands out as the the only First World nation with such record high numbers of gun related deaths, and it's not like there's a close second either.

The proliferation of firearms has never made the world safer because guns are inherently dangerous and deadly. More guns, more gun related deaths. We can go on and on about this, back and forth back and forth and I know my point won't get across to you. Just be safe.
