i usually avoid arguments on ns but you are fucking retarded.
as a disclaimer, I am liberal, and simply believe in my 2nd amendment rights. I did not sidestep you question, but repeated the actual language of a potential assault weapon ban. It is clear that you do not understand guns in general. Comparing an ar to a bolt deer rifle is like comparing afterbangs to pow skis. Both serve their purpose in different scenarios.
From what i'm gathering you think that the only scenario for an ar-15 or similar semi automatic rifle is to kill people. I do not agree that a semi-auto ar has more killing power than other rifles. In fact in close areas, a pistol has much more stopping power.
Now as you proposed, if I am going to war, and am limited to semi-auto rifles (what the ar-15 is) I may not choose it. It shoots a small round (basically a .22), and in semi auto the benefits of the m-4 platform aren't greater than most other guns. It is a low recoil gun with the ability to carry lots of ammo because the bullets are small. Nevertheless, these benefits are most noticed when the guns can fire full auto or burst, which civilian ar's don't.
I think the problem is with the publics understanding of what an "assault rifle is"
Here is a mini-14
Most would state that it is not an assault rifle, but more likely a target rifle.
This gun shoots the same round at the ar-15, and can 40 round mags clipped in. The ar-15 on the other hand looks more menacing due to it's pistol grip, adjustable stock, and magazine.
So to answer your fucking bogus question, would I choose an ar to take to war, probably. I'm comfortable with the platform, and there is a reason our military has adopted the weapon. Does this mean that killing is it's only purpose? No. Every gun has the potential to kill if someone willing to kill uses it. Hell, so does every knife, every car, and every fucking child playing goddamn lawn darts. In a crowded room, someone could kill as many people, as fast, using an semi auto ar, a pistol, a shotgun, it doesnt fucking matter. Killing power is a term that is so subjective that it hardly can be offered as the reason ar sporting rifles should be illegal. I use my gun for an inexpensive and very fun avenue for target shooting. That is it's use. I probably wouldnt hunt with it because the rounds are often considered TOO SMALL to safely take down deer. I use it for target shooting because it is inexpensive.
Say what you will, and give me some other questions you want retorted, but I don't think your argument is legitimate.
