>> The difference between us and the animals is that they lack enough intelligence to produce anything meaningful(i.e technology, innovation etc) during their lifespan thus the reason why their scope in life is to become good food for us. Same logic can be applied to children until a certain age, disabled, sick, old and/or mentally handicapped people. Kettle is easy to take advantage of, it's convenient and almost everything they "produce" can be sold (milk, meat, skin). Not showing enough compassion for sentient beings while having the ability and options to not have them as "a tasty meal" makes you a bad person in that regard. You can be social worker, a teacher, doctor or overall caring person, and have other great character traits, because nothing has to be black and white. Having superior intelligence and using that as an argument to justify exploitation of other living beings is a very sad way to look at all of this in my eyes.
