Here we go with the Second Amendment again, didn't I mention they don't understand it nor the Bill of Rights? Little history lesson for yoy
"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"
Making it real simple, since the 19th Century the Supreme Court in numerous cases interpreting the Second Amendment has never gotten beyond the prefatory clause, "a well regulated militia being necessary to the security of the free State." The prefatory clause is the purpose of the Amendment, what makes the "right of the people to keep and bear Arms shall not be infringed" relevant, and if you can't say what the prefatory clause means your just guessing on the remainder of the Amendment
The Roberts Court, owned by Scalia, figured it out by just rejecting precedent and skipping over the prefatory clause largely on the basis that it was too difficult. They ruled that if someone in DC wanted to own a gun to keep in his house for self defense it would be acceptable, a weak decision proven by the fact that the NRA has attempted numerous cases using Heller as a precedent to eliminate regulations of guns and have lost the vast majority of the cases. Even the Roberts Court has refused to hear several of them
Lastly, even Scalia warned in Heller that no right is absolute, and that the regulation of guns was totally legal
And from what I have seen, the tag Barney Fife fits perfectly, it ain't those who favor gun regulation that feel the need to assemble an arsenal in their home for protection
