It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that but it's got all the sort of terms that religions use... The greens use guilt. That just shows how religious greens are. You can't win people round by saying they are guilty for putting (carbon dioxide) in the air.
People just don't laugh when their family is violated and you don't shrug it off. You band together and you defend together. It's a funny primitive instinct.
We need a better way to talk about eating animals a way that doesn't ignore or even just shruggingly accept things like habits cravings family and history but rather incorporates them into the conversation. The more they are allowed in the more able we will be to follow our best instincts.
