You're completely missing, or deliberately ignoring, the point that those that have issues don't care what the weapon is, they're going to do what they're going to do.
Comparing them is NOT silly. It's an entirely valid point and comparison; just because people don't do it as often is immaterial. Why? Because if we look at rates of how often something happens, then you MUST look at rates of legal gun owners committing mass shootings.
So, people don't often get killed in a mass shooting by a bow?
Well, comparatively, based on number of guns owned, people get killed just as infrequently in a mass shooting by any sort of gun, much less a legally owned one.
It's the same as Great Britain with knives... take the guns, and you're not getting rid of anything but people legally owning guns. The murders will continue because PEOPLE are the problem, not the tool they choose.
