Warning: language ahead. I'm letting this clown have it with (heh) both barrels. And no, I'm not cutting it or locking it because I have had it up to here with these arrogant, clueless assholes telling me what I "need." Deal.
Just how fucking stupid are you?
You know what, wait, don't answer that, because it's on display for all and sundry this week and we can answer it for ourselves.
You said: "We live in an area that's wooded and secluded," Biden said. "I said, Jill, if there's ever a problem just walk out on the balcony here ... put that double-barreled shotgun and fire two blasts outside the house."
There are so many things wrong with this. First of all, you also state that you keep your shotguns in a locked safe. So, not only does Jill have to get to the safe (is it in your bedroom? Because ours is in the basement down two flights of stairs), she has to remember the combination, get the thing open, find the ammo (which, according to "gun safety" "experts," should be kept in a separate location from the gun), and load the thing, all while being in fear of her life. Then she should go out on the balcony and expend all her ammo in fucking warning shots.
Which, unless she's pocketed some extra shells, will now leave her helpless. That shotgun is nothing better than a club, at that point.
Not only that, but in every jurisdiction I can think of, doing that is illegal as hell. You don't shoot at something that you don't intend to kill dead. I mean, whoopdedoo, I'm so fucking glad that you live on an estate or some such shit where you don't have to worry about stray pellets hitting innocent people, but the rest of us don't have that luxury--we live in the Real World where our neighbors and their pets are right next door.
Have you ever taken a gun safety course? EVER? I just did, for my Concealed Carry Permit. And in that class, one of the first things they told us was "don't fire warning shots." Not only does it waste ammo, but bystanders can be a Thing, and firing into the air is also fucking stupid because you don't know where that round will fall. If you were paying any attention at all, you would know that. Hell, how many times do we hear in the news around the 4th of July where some drunk dumbass decided to celebrate by firing his hogleg into the air and accidentally hurt someone?
And then there's this: "You don't need an AR-15 (assault rifle). It's harder to aim. It's harder to use and in fact you don't need 30 rounds to protect yourself."
Don't tell me what I fucking need. That, sir, is not up to you. Again, maybe you live in Rich Dude LaLa Land where home invasions with multiple intruders aren't a Thing, but if I've got four people busting in through my door, I want more than two rounds that I've already expended in fucking warning shots. While it's true that your little scattergun has a wider pattern than an AR-15, this doesn't make the AR-15 any "harder to aim or to use." It is certainly easier to load if you've got a full mag right there. I would rather have 30 rounds and not need them than need them and not have them.
And guess what? Police and SWAT teams use AR-15s for... wait for it! SELF DEFENSE. And they're not walking around with fucking ten-round magazines either. So, if it's good enough for the police, it's good enough for me--because when seconds count, the cops are only minutes away. With their AR-15s.
So. Take your fucking stupid "advice" and shove it up your ass. I certainly hope that your wife is smarter than you are and doesn't actually follow it if she ever is (God forbid) confronted by armed intruders in your home.
Hugs and kisses,
