The debate over what to do to reduce gun violence in America hit an absurd low point on Wednesday when a Senate witness tried to portray a proposed new ban on assault rifles and high-capacity magazines as some sort of sexist plot that would disproportionately hurt vulnerable women and their children.

The witness was Gayle Trotter, a fellow at the Independent Women’s Forum, a right-wing public policy group that provides pseudofeminist support for extreme positions that are in fact dangerous to women. She told the Senate Judiciary Committee that the limits on firepower proposed by Dianne Feinstein, a California Democrat, would harm women because an assault weapon “in the hands of a young woman defending her babies in her home becomes a defense weapon.” She spoke of the “peace of mind” and “courage” a woman derives from “knowing she has a scary-looking gun” when she’s fighting violent criminals.

It is not at all clear where Ms. Trotter gained her insight into confrontations between women and heavily armed intruders, since it is not at all clear that sort of thing happens often. It is tempting to dismiss her notion that an AR-15 is a woman’s best friend as the kooky reflex response of someone ideologically opposed to gun control laws and who, in her case, has also been a vociferous opponent of the Violence Against Women Act, the 1994 law that assists women facing domestic violence.

But it is important to note that Ms. Trotter was chosen to testify by the committee’s Republican members, who will have a big say on what, if anything, Congress does on guns; and that her appearance before the committee was to give voice to the premise, however insupportable and dangerous it may be, that guns make women and children safer — and the more powerful the guns the better.
