If it is legal in your state to hunt over it the have at it and happy harvesting.
As to whether it is ethical or not, it is a by choice issue, if it is legal to do so.
As to those opposed to any baiting for any type of game. When was the last time you went fishing and caught something by not baiting your hook? And is it fair to the fish if you use artificial bait? At least with live bait, the fish gets a last supper. :P
