My girls like to hunt and fish...There's terabytes of misleading info on the web. As with many other fringe movements, pics and videos are taken and stretched and pulled until they don't reflect reality. There is a lot of deception out there and there are many gullible people deeply affected by it. I'm personally not puzzled at all and fully support animal husbandry and the process of providing meats from varying animals to the marketplace. Killing an animal is part of that process. I've broken a few chicken's necks in my time and then dipped the fresh carcass in boiling water before defeathering...
I am thankful to live in a time, so far, where we dont have to defeather chickens...I think it was a tough process...
