State of the States

thank goodness diapered donnie had the good sense to build that border wall in CO to keep the country of New Mexico from getting into the states!
it's funny because he really said that

he's a known geographer, that's for certain 😂

So...
If a guy crossed state lines with a gun into a state that banned guns
that would be fine because the border indicating the differentiation between those two states is legal fiction?

it would be fine because the right to keep and bear arms shall not be infringed
