Effect, meet cause:
Angry people with ready access to guns are typically young or middle-aged men, who at times lose their temper, smash and break things, or get into physical fights, according to the study co-authored by scientists at Duke, Harvard, and Columbia universities.
Study participants who owned six or more firearms were also far more likely than people with only one or two firearms to carry guns outside the home and to have a history of impulsive, angry behavior.
Cue the argument from GRNC or other firearm fetishists: "It's not against the law to be angry. At least not yet." Within that (admittedly fictional) statement is the paranoia and distrust that underlies the thought patterns of many gun enthusiasts, who are also the people who expect us to not be paranoid about them concealed carrying in parks and restaurants. But they simply can't (or won't) grasp the contradiction.
