"I don't use them and I don't like them and they look scary to folks, so they should be banned." How does that kind of attitude differentiate you from Sarah Brady? Here's a hint - it doesn't.
It's not up to you to decide what tool I should use in my hunting. For what it's worth, I have hunted for the past four years now exclusively with AR-15 pattern rifles. These rifles have been chambered in all sorts of things: 308, 7.62x39, 6.8SPC, and 223. I've used these rifles to drop numerous species of deer and a passel of feral hogs ranging in size from 120lb to over 500lbs - all on foot and most within 50 yards.
I consider the AR-15 a really useful lightweight platform that's ergonomically exceptionally well suited to still hunting. More importantly, the AR-15 platform lets me choose a number of chamberings to match the game and still be shooting the same platform with the same internal parts and the same manual-of-arms. It's a logical extension of the 'beware the man with one rifle, because he probably knows how to use it' philosophy, only extended to incorporate multiple chamberings to better match the game being hunted.
I could probably assemble a similar toolchest of shootin' irons out of Browning BARs or Remington 7400s (and therefore placate your need for a 'traditional looking rifle'). But I don't shoot them as well as I shoot the AR, so why would I choose a tool that doesn't work as well for me based solely upon aesthetics?
I don't mind you using a wood-n-blued-steel boltgun; why begrudge me my choice of tool? Freedom is as freedom does. If you don't step up and defend ALL kinds of rifles, pretty soon you won't have ANY to defend. And the legal gap between an AR-15 and a BAR is a lot smaller than you think...
If you have an issue with slob hunters, call 'em out for what they are regardless of what they carry. But anyone that insinuates that having multiple rounds at my disposal somehow makes me more liable to shoot indiscriminately is frankly talking about things with which they have little practical experience. An ethical hunter is an ethical hunter regardless of chosen tool. And certainly, the converse is also true - a slob hunter is a slob hunter regardless of whether they use an AKM-47 or a Cooper.
Sometimes gunowners are our own worst enemy.
