I wouldn't say that.
I doubt that someone who has a room full of guns is going to take an AK deer hunting. A Saiga yes, an SKS sure, but not a military-configuration AK. I think pistol grips are a liability, not an asset, in the field.
At last count, I have somewhere on the far side of 200 boomsticks in my collection. Last fall, I took a Wisconsin whitetail with my sidefolder AK and 125gr softpoint handloads. One shot in the breadbasket, and he was down. As for the pistol grip, I'll have to remind myself about the whole liability thing, because it caused me no problems, and I gave it nary a thought when I squeezed the trigger.
Why did I use the AK instead of my usual Browning BAR, Remington 700 BDL, Winchester 94, or BSA No5Mk1? Because of folks like Zumbo, and the unbelievably hypocritical hissy fit that some have over learning that the AK works just fine in the whitetail woods. Myself, I wanted to prove the naysayers wrong, and I was pleasantly surprised by the results. I may take a Kalashnikov out into the woods this coming fall, too. I'll use it for supplemental doe tags.
BTW, I have a family friend who is a DNR game warden. Contrary to popular belief, he wasn't too upset to see an AK in his district - far from it. It's no different to him than were the fellow carrying an old Winchester or Marlin levergun. He's more worried that the hunter isn't carrying, or doesn't have, the proper hunting license. Poachers make him mad.
Honestly, sometimes the "stigma" attached to a gun extends only as far as those who would continue to propogate the myths. Those who do so often forget that their beloved tools for harvesting game are little more than spiffied-up variants of a previous generations' battle weapons, "good for hunting people". Oh, the shame.
