"YOU LOST AGAIN"??? The U.S. Supreme Court, the highest authoritative Court in our nation, has ALREADY upheld the right of CITIZENS to keep and bear (carry) arms! They also upheld the rest of the 2nd Amendment, which states "SHALL NOT BE INFRINGED," when they BANNED states from allowing "conceal/carry" and they banned states from "highly restrictive gun laws."
You see, that wording, in itself, makes it TRICKY at best to even "amend" the 2nd. Amendment!
You'll also notice that no other Amendment ends with that "wording," making the 2nd Amendment a very unique "right." Our Founders weren't STUPID, like our current day politicians!!!!
