In 2019. Not in 1791. And the militia is to be regulated. Not the right to bear arms.
“A well-regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”
The militia is "the people", not a formal entity. The right to bear arms not being infringed is a required limitation on any regulation or organization.
Quit cherry picking to suit your own twisted desires.
