I agree! The stance in that article seems very "unfeminist". As men, we are constantly criticized by feminists for being fearful of "strong women", like, supposedly Hillary Clinton, but the feminists that are more socialistic aren't really feminist. Such is the case with the writer. "Women can't use guns", uter nonsense! My very "unfeminist" grandmother could use a gun, could hunt, and knew how to prepare game and poultry. The current crop of pretend feminists are wimpy socialists who whine about motherhood being akin to slavery, have a patholigical fear of guns, and want the federal government to replace the husband or father that they shun. This is the overall tone of the piece.
More specifically, it is erroneous and like most antigun rhetoric purposely intended to mislead. I haven't seen the movie, so I can't comment on the character being a "vigilante". Perhaps that is only an interpretation. No. I wouldn't expect most women to become vigilantes, but comparing THAT to women defending themselves with firearms is very misleading.
I also take exception to the equally dishonest practice of anti-gunners to lump criminal behavior and legitimate behavior together. But this is intentional!!! The infamous "kellerman report" was almost exclusively about criminal and crime victims, that's why its conclusions are invalid. Almost ALL murders are committed by individuals with a criminal history. Almost all firearms accidents involve the same individuals with criminal or drug abuse backgrounds. Thus, in discussing women using guns defensively and legally, those statistics are irrelevant.
Another problem is phoney connections between guns and suicides of women. Women don't often use firearms to commit suicide, so I would like the author to explain to me, how the simple presence of a gun causes more suicides. I haven't seen the study, but I would bet that it is similiar to the Kellerman report, where factors like criminal history and drug abuse are ignored as causes for homicides, and only the gun is relevant.
The last major problem occurs with defensive gun uses. Using a gun in self defense, potentially saves the life of the potential victim, but it more than often saves the life of the criminal as well. The prevented murder or the prevented justifiable homicide can't be counted. It is easy to see why: the criminal sees the armed citizen and flees the scene, and the crime doesn't occur. The criminal lives to either change his criminal operations or looks for an antigun feminist to victimize. The potential victim doesn't shoot the criminal in the back, because it is illegal and he trys to abide by the law.
