I understand that people who love animals want non-human animal rights, but along with animal rights comes a bunch a consequences. For example, if all animals were treated with nothing other than kindness, then there would be no zoos, no animal entertainment, no animal tests, no animal fur for clothes, no hunting, no medicine, no fresh meat, and no hard labor done. If you think hard about it, animals were not created to be kind to but to do our hard work, give us medicine, clothes, food etc.
Philosophers have stayed away from arguing about animal rights because of the consequences are so limiting for humanity. I think that only adult animals should have rights because they are ‘subjects-of-a-life’.
People who love animals should start facing the facts that this world is not all kindness to animals and no abuse, because it isn’t, we need animals to survive.
