Trucks don’t have brains either

The writer tries to argue that, because guns don’t kill people but rather people kill people, the ridiculous ease with which any American can buy a gun is actually not the reason the country has the single worst gun-homicide record globally. Nor is it a factor that the US has such a huge marketplace for firearms.
He says trucks can kill people more effectively. Does he not realise that there are huge numbers of trucks in the US? Yet how many trucks have been used to kill in that country? In comparison, how many people have been killed with guns?
I presume the writer is an American. He accuses another writer of being short-sighted on this issue. 
I find it incredible that many Americans cannot see that their collective acceptance of guns in their society is the sole reason for the massive rate of gun deaths. Who really are the myopic ones – Americans or literally the rest of the world, including Canada?
