I've unfortunately been away far too long to respond to anything specific, IMO. All I can say is that it seems quite a few people don't know what hunting actually is. This is not surprising, of course. Typically the loudest opinions against something come from those with the least understanding of the topic.
People don't need to hunt for food in most places, no. They do need to hunt, though, to keep wildlife numbers from exploding past sustainable levels. Our ancestors removed most natural predators (other than us) so we fill in the gap. We've tried reintroducing these predator species and have found that we don't really know what we're doing.
Anyone who thinks hunting is something that should be banned because of its violent aspects had best be a vegan - and a real one - or STFU. Srsly. And even if you are a vegan I can tell you how much animal blood is on your hands anyway. The reason I feel this way is that if you eat meat you are responsible for violent death. You are also responsible in many cases for deplorable living conditions and harsh treatment. Hunters, at least, look their food in the eye before it dies.
There's more but whatever.
EDIT: Forgot one:
Hunting is expensive. Well, it sure can be. Resident tags don't often cost a lot but you need more than a tag, a loincloth and a sharp stick to hunt these days. Bows and guns cost hundreds to thousands of dollars. You need arrows and ammo, too. Hunting clothes can be several hundred dollars for one piece. I was just hunting yesterday and my kit included a $450 gun topped by a $300 scope, a $250 range finder, a $50 backpack, a $300 parka, a $300 set of bibs, a $100 set of goose down and some other stuff. It ain't a cheap hobby.
That said, it's also totally not at all what I was talking about. Piling in the pickup (mine, used, was $12,000) and heading to the family friend's farm is a wholly different venture from globetrotting to hunt. An either sex deer tag cost me $24. To hunt a Greater Kudu in South Africa you're looking at over two thousand dollars. And that's not considering the plane ticket, lodging, guide fees, etc. Many animals in Africa and even the US cost five figures to hunt. Cheap? Nope. At least not for me.
