You have quite a few absolutes in this comment, and not all of them are correct.
Having access to a gun does statistically make you more likely to die of a gunshot, including significantly higher rates of suicide.
HOWEVER, stating that there are zero situations where having a gun would be better than not having a gun is just incorrect. It is highly unlikely for a gun to improve a situation, and it is an anomaly for a gun to make a difference, but there are well documented instances where a gun prevented the start of, or the continuation of, violence.
Flatly stating that there are no situations where a gun can make you safer is untrue. Pushing this hyperbole only helps keep the conversation on the wrong topics.
