As a boy, my family kept chickens and rabbits. Now I'll give you a minute to guess what sometimes happened to chickens and what always happened to rabbits.
That said, the realities of eating meat are what they are, and I understand them. Animals have to die if you're going to eat them and I've seen them killed. Videos like this won't change my mind. Good people should feel sympathy for animals I feel however and I don't blame anyone for getting upset. If people are treating animals inhumanely, or being extraordinarily cruel, well there's just no need for that. I'll also agree that there's just no need to eat dolphins. Something that smart shouldn't be on the menu.
As for the rest, not watching the video because I don't need a one sided rant citing the most ridiculous examples. I guarantee you there are more efficient means to killing an animal than an electric prod up the anus.
