This is so funny. The right to keep and bear arms doesn't have anything to do with carrying arms.
Then what, exactly, does the word "bear" mean?
Let me first start explaining how the English language works, just for clarification and to make a point.
If you have the word "stool" for example.
"stool" means "a piece of solid waste from someone’s body"
So, we have a story "John walked into the bar and sat down on the wooden stool with three legs".
Do we believe that this stool in the bar was a piece of solid waste from someone's body that was made of wood and had three legs? No we don't. We know this is "a seat that has legs but no support for your back or arms"
The point being that just because "stool" can mean "shit", it doesn't mean it does every time.
So.... bear can mean carry. In the context of "bear arms" it does not mean carry and never has.
The easiest way to define "bear arms" is to look at how the Founding Fathers used it.
Amendment II: House of Representatives, Amendments to the Constitution
""A well regulated militia, composed of the body of the people, being the best security of a free state, the right of the people to keep and bear arms shall not be infringed; but no person religiously scrupulous shall be compelled to bear arms.""
They were discussing the last clause of this proposal of what would become the 2A.
See the last part, religiously scrupulous people would not be compelled to "bear arms".
Mr Gerry said: "Now, if we give a discretionary power to exclude those from militia duty who have religious scruples, we may as well make no provision on this head. "
So he's using the term "militia duty" synonymously with "bear arms".
Mr Jackson said: "No one, religiously scrupulous of bearing arms, shall be compelled to render military service, in person, upon paying an equivalent."
He used "render military service" synonymously with "bear arms".
At this time, "bear arms" meant to be in military service, in this context it was rendering military service in the militia.
That is what "bear arms" means.
