Veganism is not exclusively for the overly-sensitive or for the people that grew up with glittery kittens on their school folders. It is a natural step we take when we start to act on our empathy. Veganism is morality in action. We stop supporting the exploitation of animals not because they are cute, cuddly, and silly, but because a difference in species does not translate to a difference in how one should be treated.
Consider this: We can’t personally love every human on this planet, and I’m sure there are many that we wouldn’t even care for, but it’s wrong to intentionally harm or exploit humans nonetheless. Rape, slavery, abuse — none of it is ever justifiable. This is not because we personally love the people that suffer this abuse (like we love our individual pets), but because every living being should be free from torture, free from exploitation, free from intentional suffering at the hands of another.
