That’s an incorrect statement. Let’s look at the evidence.
More than 50 million Americans engaged in some kind of recreational shooting in 2018 [0]. Compare that to 14,000 gun-related homicides across the country in the same period [1], mostly in certain high-crime communities [2].
The CDC estimates there are between 500,000 and 3 million instances of defensive gun use in the US each year [3]. They also found that cases of self-defense where the victim used a gun resulted in less injury to the victim, on average, than in cases where other self-defense strategies where employed.
There are also obvious downsides to a society with permissive gun ownership, but overstating the case for gun control doesn’t move the discussion in a positive direction.
