It is by no means clear that rounds fired by a semiautomatic rifle are deadlier than rounds fired by a handgun (BTW, the rifle used in Orlando was *not* an AR-15, but these comments work broadly across different rifle designs). Rifles differ from handguns in a variety of manners - in general, they have higher muzzle velocities, better accuracy, and longer ranges. Yet their deadliness has a lot more to do with the skill of the shooter and the type of ammunition than with the firearm choice. Famously, the M-16 in widespread use by the US and other armed forces (and the basis for the civilian AR-15) has at times been criticized for putting holes in people but not putting them 'down' - i.e. while it's a very powerful weapon, its stopping power is limited. Bullets that fragment or otherwise change on impact cause a given weapon to have much greater stopping power; also, higher calibers may be more deadly, though the actual details are complex.
Furthermore, it is not at all clear that a semiautomatic rifle would be favored over a smaller weapon for producing maximal casualties at a mass shooting. Rifles are useful for long ranges, and (automatic) rifles are useful for needing to unload a lot of lead quickly. But smaller weapons - whether handguns or machine pistols or shorter rifled weapons like bullpup or carbine designs - work much better in confined spaces than a bulky full-size rifle. Several militaries and branches of militaries have moved to compact primary weapons due to changing battlefields, especially as one gets into urban warfare - they aren't relying on handguns, of course, but they are using much smaller weapons than people typically think of when we talk about assault weapons. Many civilian 'assault weapons' are carbine designs, so they're a bit shorter, but far from the most easily maneuvered in tight spaces. I would imagine that if a trained operator was trying to kill everyone in a small space, they'd use a machine pistol or the like loaded with appropriate ammunition. Fortunately mass shooters are rarely trained and frequently nuts - that means that they buy scary looking guns but aren't necessarily optimizing their weaponry for the planned attack. It also suggests that appropriate policy might not just focus on specific weapons but more broadly on the availability of firearms as a whole.
All of the current suggestions - such as outlawing high capacity magazines or certain classes of rifles - are nibbling at the edges of a much bigger problem. Let's be honest about it and try to actually change things.
I think the fundamental difference here is that it's hard to imagine a circumstance where many firearms could be used without harming someone. Your argument works well for an object that has intrinsic worth or usefulness outside of killing people. When it doesn't, such as with firearms, the case must be made to keep them, rather than to outlaw them - even if the incidence of deaths per weapon is quite low.
