On the other hand so far today more people have died on America's roads than died in the Orlando shooting. I don't hear any calls to ban cars.
What a ridiculous thing to say.
Cars serve a useful purpose in society. Cars are primarily a mode of transport. They serve a purpose that people find useful. As such, their use supports the economy, facilitating creation of jobs and transportation of goods and so on. Most people who are involved with cars enjoy uneventful journeys. When used as intended by the manufacturer, cars do not cause direct physical harm.
Guns do not serve a useful purpose in society. They are primarily weapons, which are designed to maim or kill when used as intended by the manufacturer. They do not serve any other purpose. Their use does not support the economy, as their effects limit their victims ability to be economically useful.
As cars are a useful thing in society, it is worthwhile trying to prevent injuries and deaths whilst continuing to allow their use. As guns are not a useful thing in society, it is not worthwhile continuing to allow their use - on the contrary, it is the most sensible approach to restrict their use with the express purpose of preventing injury and death.
When the intended effect of the object in question is the effect that you are trying to prevent, it would be foolish to allow the objects continued use. Surely you can see that, whilst guns and cars can kill people, only one of those objects is primarily used with the intent of doing so.
