You have NOT "proven" me wrong. Making words mean what you WANT them to mean does not prove a contention. Nor does your opinion mean anything to me. Nor do your insults nail down an argument even if Bert applauds them.
"To preserve liberty, it is essential that the whole body of people always possess arms, and be taught alike, especially when young, how to use them..."
(Richard Henery Lee, 1788, Initiator of the Declaration of Independence, and member of the first Senate, which passed the Bill of Rights.)
"That the said Constitution shall never be construed to authorize Congress to infringe the just liberty of the press or the rights of conscience; or to prevent the people of The United States who are peaceable citizens from keeping their own arms..."
(Samuel Adams)
"The people are not to be disarmed of their weapons. They are left in full posession of them."
Zachariah Johnson Elliot's Debates, vol. 3 "The Debates in the Several State Conventions on the Adoption of the Federal Constitution."
You talk of the importance of the meaning of words, yet still fail to provide a definition of "arms" as understood by the Founding Fathers.
Again: those guys just went thru a war and owned cannons themselves; give a SINGLE quote from them indicating they did not consider cannons to be "arms".
