Animals abuse animals more than any person ever could.
Which animals are you talking about?
Cows? Sheep? Pigs?
Because human are mainly abusing these specific animals.
And besides we human have quarrels in our families. We fight, we make peace etc. But would you change this life with fights and quarrels and hard work for a peacefully but dull life in prison? Where you have no worries but to eat, sleep and shit.. and the only price is your life when you become mature enough... just imagine you have these 2 choices
Freedom and problems OR careless dull life in prison.
OK so now imagine some creatures so advanced that humans in comparison to them are like animals in comparison to us.. (that's just an example, I don't personally believe that we are very superior to animals) and these cool creatures decide that it will be better if we were in prison, taken care of otherwise we will destroy our world and ourselves. Would you give these creatures the power and authority We have over animals?
