What a lousy argument you make! We all possess the potential ability to yell "FIRE!" in a crowded theater (when there isn't, in fact, a fire, and we know such to be the case). However, that doesn't give the government the power to surgically remove one's vocal cords or rip out one's tongue in order to stop us from endangering or infringing upon the rights of others.
Gun control is to the Second Amendment as the forced removal of your vocal cords or ripping out of your tongue is to the First Amendment.
The point is that every right protected by the Constitution permits reasonable regulation to ensure that society as a whole is protected. Don't like the fire argument? Then how about all the licensing requirements for the print and broadcast media. Isn't that an infringement? How about having to get a permit to peacefully assemble? Where are those requirements mentioned in the Constitution?
