I suppose the counter-argument to that is that the number of homicides actually committed with the above-mentioned methods aren’t remotely comparable either.
That is one common argument, and that common argument shows my point well.
The fact that people, as you point out, argue against guns due to the deadliness of the weapon. Then refuse to apply that same concern on more deadly things then that means the deadliness of the weapon isnt the issue, they dont mind more dangerous things being accessible. So now the argument becomes “this weapon is used to hurt more people than other more deadly weapons, so THAT is the reason it should be illegal.
Then this logic likewise fails in fantastic fashion. Melee weapons are the most commonly form of weapon used in the USA (bats, blunt objects, knives, etc) for assaults and violence (which would include homicide) Melee for example is ~160K a year where handguns are ~150K a year.
So again if logic was actually applied consistently then melee weapons, being the weapon most often used to inflict violence would be our top concern and most regulated form of weapons, not guns.
If there were a rash of high-profile mass-poisonings, I’d wager the same people would be calling for tighter restrictions.
There is already a consistent pattern of other weapons being used for violence more often than handguns.. I dont hear the screams to regulate bats or knives.
