Gun Control Cultists like to repeatedly point this out to anyone and everyone.
"The Second Amendments has no place in today's society," they say. "It's a product of a bygone era and means nothing in the modern world. It refers only to muskets and other old-style weapons. The Founders could not have forseen the development of semi-automatic pistols and their like. It's obsolete. Therefore we must repeal it."
The Founders also could not have forseen the development of television, movies, and the Internet.
Yet we still apply freedom of speech and freedom of the press from the First Amendment to those inventions.
But in the era of the Founders, press and speech was limited to voice, hand-written literature, and anything made by the printing press.
Nothing at all remotely like CNN, Google, or the latest Steven Spielberg flick.
Therefore we should prohibit the use of First Amendment freedoms to television, movies, and the Internet.
