what a stupid mindset. Show me a time someone managed to kill 20-50 people in a span of 15-30 minutes with a bow, let alone a knife, let alone a laymen that didn’t have military training.

As an aside the goal does not have to be to solve the problem definitively. It can be to make the problem markedly better. If mass shootings with body counts in the above turned into mass stabbings, which are obviously traumatic and horrible but typically have fatalities in the single digits (often only 1-2), is that not a tremendous improvement? It is of course still very worthwhile to address systemic factors that lead to violence, but making violence less severe is worthwhile as well.
