Can the 2nd amendment distinguish between unloaded firearms and loaded firearms?

In the past, firearms were only loaded immediately before being used; the technology for firearms in the 18th century had few pre-loaded firearms in public. Having a policy affecting loaded firearms differently than loaded firearms just might pass muster as consistent with past firearm practices.

Displaying this green pentagonal sign would alert people that a building or event does not allow loaded firearms. Regular pentagons are not symbols for any other purpose and the green color symbolizes a focus on life.

To use these signs would not need any new legislation. Going to a place displaying the green pent with a loaded gun would be a form trespass (and in many places, felony trespass). Trespass laws are pretty straightforward. Bringing something to a place where you are not permitted to have it is trespass. However, legislation could codify the sign’s meaning.

These signs could be self-enforcing. A person carrying a loaded firearm generally won’t want to have an unpleasant interaction about it. If the signs were widespread, there shouldn’t be a paradoxical response where it would promote the opposite behavior. Firing a gun at the sign would quickly lose novelty. Open carry would be deprecated by people without guns.

This seems like a way of hacking the 2nd amendment to reduce the presence of dangerous loaded guns in public spaces. It would be a way of offering a new policy and starting a new conversation about the meaning of American gun violence.

Wearing a green pentagon is a way of taking a stand.
