RE: using bait
Baiting is fine, unless it is illegal where you live. This is the same debate as bows vs. crossbows, and rifles vs. shotguns/ muzzleoaders. You don't here golfers arguing over whether using metal woods is unethical. If you don't like baiting, then don't bait. One of the great things about hunting is you get to set (most of) your own rules.
