Why do people get confused about the relationship between the Second Ammendment and the slogan 'Gun Control'?

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

The Second Ammendment is the law of the land. Nobody will get anywhere at all arguing that people may not legally own firearms.

On the other hand, ‘Gun Control’ is a slogan. It is, I believe, designed to make people believe that there is no place for debate about what weapons may be possessed to serve the interests of the People, and what weapons may be restricted in order to serve the interests of the People.

I appreciate that politicians play word tricks every day. That is what they do. They are jokers and liars and ambitious egotists, and that is what they do.

But what is wrong with the People? How did it come to pass that they do not understand the difference?
