No one suggests killing homeless people, however inconvenient they are.
But convenience is the reason homeless dogs and cats are murdered every day across the country and around the world.
Convenience and cost. People value money over the lives of homeless companion animals. They do not wish to be bothered with providing them food, shelter, veterinary care. It is too much of a burden to train caretakers and advocates, too expensive to advertise for new homes, a drain on resources to spay and neuter.
Much easier to just kill them. And cheaper.
Even some animal people swallow the propaganda of conservatives who cheerlead the extermination.
Newsflash!: dogs and cats are worth more than tax dollars or conservative ideology!
The distinction is based upon speciesism, the belief that some lives are more valuable than are others of a different species. And the argument can easily be made that people have a greater responsibility to abandoned and homeless animals than they do to homeless and abandoned people, if only based upon the fact that homeless animals are incapable of helping themselves.
Humans domesticated the dog. They bred dogs to serve them, to keep them company, to entertain them, to protect them, and to work for them. Humans took dogs out of the wild and made it impossible for dogs to survive without humans.
In so doing, human society should be responsible for the entire population of dogs. And for the entire populations of any animals they have enslaved, genetically altered, selectively bred, or in any way whatsoever made impossible for such animals to survive in nature.
Every single one of those animals and their offspring are entitled to be cared for by human society.
Whatever the cost in taxes, staffing, training, and medical care, every single unwanted animal has the right to live, and human society has the responsibility to keep them alive, safe, and healthy, just it has the same responsibility to unwanted people.
We have made animals our slaves and our companions, and their well being is human responsibility.
So long as society continues to possess animals, and so long as our law permits it, so should our law require that food, shelter, and medical care be made available to any animal that needs it.
