He most certainly never said "wildly and blindly", you just made that up. He even prefaced buy saying they lived in a secluded area. And nobody is arguing that Biden is the greatest speaker in the world.
If you want to protect yourself, get a double-barrelled shotgun, have the shells, a 12-gauge shotgun, and I promise you, as I told my wife — we live in an area that’s wooded and somewhat secluded — I said “Jill, if there’s ever a problem just walk out on the balcony here, walk out, put that double-barrelled shotgun and fire two blasts outside the house.” I promise you, whoever’s coming in is not — you don’t need an AR-15. It’s harder to aim, it’s harder to use, and in fact you don’t need 30 rounds to protect yourself. Buy a shotgun. Buy a shotgun.
