No, it's not hunting and yes it is a valid form of pest control. But I wouldn't go so far as to shame them. Having been on many hog hunts with the old man and seeing the severe damage hogs do to their environment, I am 100% in favor of any legal method to take those hogs out. And you do have to kind of hunt them, then herd them with the chopper. Then it takes a pretty damn good shooter to take out running hogs from a moving chopper. This chopper hogs thing is something I really want to do one day. Looks like tons of fun and, if done properly, can put a ton of meat in the freezer in a very short time.
