I mean most pro-gun arguments boil down to “guns are needed because the only thing that stops a bad guy with a gun is a good guy with one”, so when a large proponent of this argument is thrown into a situation where he could be the “good guy with a gun” and he instead runs away because he values his own life more than protecting the lives of those around him, maybe he should stop and dwell on that thought for a minute.
Would I charge headfirst into gunfire? Absolutely not, and thats why I advocate for more gun control.
