speech restriction involves USE, gun restrictions involve POSSESSION
you cannot scream FIRE in a crowded theater (unless its a movie set or there is a fire)
You of course POSSESS the ability to scream fire to your heart's content in your own basement, or in the middle of some deserted woods.
Gun restrictions are akin to saying you can never scream fire
and everything WRONG you can USE a gun for is ALREADY illegal
Neither side in an argument can find the truth when both make an absolute claim on it.
