Hunting does not bother me when the kill is actually used for something - food, fur, or if it is legitimate population control.
I do not support "canned" hunting, where it's basically set up to where an animal is in an enclosed area or was basically farm-raised and turned loose for someone to "hunt."
Recently, a guy was sentenced to jail time and fined for killing elk in Pennsylvania. I've been to that area - the elk do not fear people, they are practically a tourist attraction, people feed them from their homes. We stayed at a campground/horseman's camp and the bull and cow elk would come right into camp. One evening I went out to find two young bull elk lying down calmly near the truck. They just looked at me, and I was only a few feet away. "Hunting" one of those would be like walking up to a cow in a pasture and shooting it. No "sport" at all.
Many of my friends hunt and fish, all "legally," they stock their freezers with enough meat to feed their family for a year, full of turkey and deer and whatever else they catch in season. Not sure I could ever be one to pull the trigger or release the arrow, but it does not bother me that other people do. The wild animals likely had a better quality of life than most of the factory-farm raised critters that end up in the meat section at your local grocery store.
