tl dr but based on the comments of clear thinkers such as ChrisL its the normal anti gun psychobabble that has been rejected by the rationalThis argument is a waste of time. It's circular. Here's how this works:
"Nobody needs a Bushmaster"
"You have no right to say what I need"
"But you don't need it. And it is more dangerous than other guns"
"Handguns kills more people than bushmasters"
"But Bushmasters are more deadly than handguns"
"Handguns kill more people, so it's a waste of time to ban the AR-15 and other whatever weapons"
"But there's no reason not to do it"
"So that's the logic?"
"The logic is that you don't need a Bushmaster"
So I will address your points:
Actually, you're the one that fears guns, because you have a gun due to your fear that somebody with a gun will attack you. I have nothing against somebody having a gun for the "just in case," but when people are arguing that every citizen needs a handgun, that's what fear sounds like. You can be responsible and have a plan for incidents such as break-ins without having a gun. You can also be very irresponsible with a handgun for self defense, as is evidenced by a handful of very recent stories around my home town regarding children shooting themselves and a crazy old man executing a 17 year old unarmed girl dying in his basement whom he had already shot.
But "you're just ready," right? Do you think parents who let their children drink pop are irresponsible? Or who let their children eat steak? Or who let their children ride bicycles? I bet you don't, because that's crazy, right? You have to be reasonable. Just like the fact that you have to be reasonable about what situations might come up in which you need self defense. You don't need a bushmaster for self defense. The only reason you'd need a bushmaster is if you needed to kill more people in less time, which is what psychopaths need, not citizens protecting their families.
I'm not afraid of criminals, which is why I can rationally say that I will never, ever, ever need an ar-15. And NEITHER DO YOU but it is MORE DANGEROUS when in the hands of CRIMINALS so STOP THIS RIDICULOUS ARGUMENT. This is about common sense. How about this: god would have given men guns for arms if he wanted us to shoot people. Would Jesus have shot first and asked questions later? Are you going for the Waco thing? Did those guys seem pretty pious? The religious argument is pretty weak, IMHO.
