I don't know why I'm wading in on this, but speaking of shooting turkeys, I saw a hunting show recently where a gal was bowhunting turkeys, and she was using a mating hen decoy that lies flat on the ground. This old tom came up and straddled the decoy and started enjoying his bit of strange plastic turkey tail, and then Wham! came the arrow. I know I know, nothing wrong with that, etc., but man, that one made me wince...
Debating punt gun ethics or whether it is a sport is no different than other hunting ethics debates, and whether or not a dead bird/game animal is really just a dead bird/game animal. Local traditions and history notwithstanding, it's all about whether or not the end justifies the means, which seems to have always been a slippery slope for us to grapple with collectively, indeed.
