While you are not wrong that there are other ways to commit mass killings, in pretty much all countries with no guns, you don't see these alternate events. So the outcomes you suggest are perhaps not the logical outcome of removing guns from society. As an example if I take Europe as a whole (the bits not in an active conflict) there aren't 600 events a year of water poisoning or trucks in crowds etc. Now true, they have different approaches to handling mental illness, so that's a factor, but even so.
