Not much different than raising game birds, putting them in a paint shaker and planting them in a field for guys to hunt. Hunting them is not the same as wild birds but its the only practical choice for many and many of us have done it and enjoy it. What about stocked trout? These animals are raised just so we can catch/shoot/consume them,
Just saying, we have many examples of similar enough examples that many of us enjoy. Not going to look down at someone that does any hunt that is legal. IMO the antler hunts dredge up the same envy we see with auction tags, guided hunts, expensive reservation hunts, etc.
To each his own - don't let the anti's divide us.
