They just aren't comparable imo, firearms are designed to do damage or kill things, the fact that they can also be used to do those very activities in a recreational setting doesn't change that.Firearms are also safe the vast majority of the time and largely used for recreational purposes, most dangerous pets originate from an animal with features optimised to kill.
In countries with reasonable firearms restrictions mass shootings are exceedingly rare.
Quite a few people get seriously injured or killed by dangerous pets each year, not uncommonly younger relatives of irresponsible pet owners, but dangerous animals are just one potential example used to illustrate the logic, you could apply the same to baseball bats, etc. (and an emerging interesting situation with drones).
A car's primary purpose is to transport things.
A baseball bat's primary purpose is to hit baseballs.
Heck, the protection aspect of firearms is still directly linked to the point that they damage/kill, much like aggressive guard dogs (which I also think should be banned from gen pop ownership).
