Most kids/adults I know who don't like hunting/fishing don't like it because the adult that initially took them sucked at it, and made it a horrible experience. Get good at it, and ANY kid will want to go.
OK, but Give a kid a slingshot or BB gun or better yet, let him get his own, and there's a damned good chance he/she will like to hunt. The TYPE of hunting and the TOOLS and the SUCCESS may vary, but love of hunt comes from the exploration, the wander, the wonder... much of which is lost when kids are over coddled or are not "permitted" to do stuff on their own.
