Most people say they are against cruelty, including cruelty to animals. Many people say they love animals. Yet these same people often eat animals.
This is cognitive dissonance. Think about it - how can it ever be anything but cruel to kill someone who does not want to die? The animals we raise for food - cows, pigs, chickens, turkeys, goats, lambs, ducks, fish, crabs, lobsters and others never "give" their lives willingly. They must be caged, caught, subdued, overpowered, dominated, manipulated. They very clearly do not want to die.
The most highly valued thing we can cruelly take from another is his/her life.
Caging others, breeding them, stealing their eggs or stealing their children so we can then steal those children's milk is terribly cruel - depraved, actually. This applies to animals too.
Paying others to do the grisly work of exploitation and slaughter so we do not have to, does not absolve us of complicit responsibility. We are still cruel. We are still paying for it, supporting it with our choices. Whether we intend to or not, if we eat animals, we are aiding and abetting horrific cruelty. We are hiring hitmen.
We are particularly cruel, if we have been made aware of the fact that we need not eat a single thing that comes from animals, and yet we still insist on eating them. At that point it is merely selfish desire that we are feeding, not any need for actual nutrients.
We should all examine our habits and beliefs. If we genuinely want to live a life against cruelty, we cannot be two-faced about it. It is certainly not "love" by any stretch of the imagination to raise animals only to exploit and kill them. We must be vegan. Anything else is vicious and sadistic.
