Final answer:
An animal rights activist differs from an animal welfare activist in that the former believes killing an animal for meat is animal cruelty, due to the conviction that animals should have similar rights as humans and not be used for consumption or research.
Step-by-step explanation:
The key distinction between how an animal rights activist feels about an animal welfare activist's beliefs is that the animal rights activist would believe an animal welfare activist does not go far enough in protecting animals. Specifically, an animal rights activist would likely think an animal welfare activist does not recognize that killing an animal for meat is a form of animal cruelty. This belief stems from the animal rights perspective that animals have inherent rights just like humans, and thus, they should not be used for food, clothing, experimentation, or entertainment.
In contrast, animal welfare activists typically focus on the well-being and humane treatment of animals without necessarily advocating for the same rights as humans. They may not oppose the use of animals for meat or research as long as the animals are treated in a humane way that minimizes suffering. This perspective is based on the view that while animals deserve protection and care, their use by humans can be ethically acceptable under certain conditions.
