The second amendment refers to a well regulated militia and bearing arms. It’s gives the right to possess guns by militia members.
The Second Amendment also states its purpose expressly: to protect the security of the state. If the “let everyone have whatever guns” approach is a threat to state security, then obviously that approach isn’t protected by the Second Amendment.
Your version of the Second Amendment is a right-wing lie, not borne out by law books, history books, or dictionaries.
