I give up. The thread is about "Do Animals Have Rights" and you keep challenging people for avoiding questions about should, and haranguing them because they are staying on topic with Do."
As has already been noted, the answer is different if one makes a distinction between moral and legal rights. If the question asks whether they have legal rights, then there is NO DISCUSSION TO BE HAD. At the present time, they have only a few 'rights' in this sense depending on the desires and whims of humans. QED. End of Thread. Cail could have answered the question himself. However, the article he posted discusses unequal treatment and ethically relevant differences which invokes moral rights. As Mighara affirms, 'legal rights' are predicated on moral rights:
That is, saying, "I have a legal right to X," implies, "I should have X."
As to the culling of the herds, if they starve to death in large numbers, it is a danger of disease for both Humans and Animals.
Exactly the same can be said about famines involving humans. We have procedures for managing disease, but at present these procedures do not involve murdering people.
Incidentally, animal rights theory does distinguish between animals which do and don't represent a threat to moral agents.
"Of course we need to decide to decide what is best for animals, we are the Species in charge of the Planet, and they can't tell us their choices."
We CAN make claims about what is best for moral patients (including animals). Children and some other humans can't tell us their choices either. I don't see how 'what is best for someone' can be twisted to mean killing and eating them, using them as scientific tools to benefit others or forcing them to provide amusement for others. 'Mercy killing' has a very specific meaning and is not usually performed on healthy people. If it is, we refer to it as killing...which is not a "humane service".
Self-appointed species 'in charge of the planet', lol.
You and Mighara are fond of Invoking Natural, Moral, etc Laws. Survival of the Fittest is THE LAW OF NATURE, that's treating Animals equally, and acting just like Animals, just as you continue asking. Lions don't think a thing about eating Gazelle, or Foxes eating Chickens, if we're supposed to be equals, why is it wrong for us to?
I have already addressed those points. Also, see the difference between moral agents and moral patients.

What you (and Dawkins, and Regan) apparently fail to understand is that deer (or fish, or cows, or dogs) are not human. It's a circular argument you make, and it's really not worth debating.
People have explained why they believe what they believe, and you've dismissed them out of hand, and responded with quotes from other people. That's cool, but it doesn't bolster your position.
You want to be nice to animals, that's fine. The second you start treating animals as equal to humans, you've crossed a line that's dangerously close to sociopathy.
Cail, I understand that animals are not human. You are claiming that humans are more worthy (and due better treatment) than all animals. I simply expect you to explain what it is about humans that makes them more worthy. You're not the only one who believes that your claim is self-evident. The same logic (reference to a qualitative class, rather than the individual qualities of the members of that class) is used to defend racism. You say 'animals are not human', racists say 'asians are not caucasian'. If we accept that 'not being human' is a valid reason to discriminate without any discussion, then we have no reason to doubt that 'not being caucasian' is a valid reason to discriminate without any discussion either.
As for the jibe about sociopathy, sociopathy usually entails the absence of empathy with others. It is more commonly associated with those who do horrible things to animals and/or people. Since I don't accept that the way another being tastes or looks is a good basis for deciding the way we should treat it, I think that makes me more empathetic than you.

Fist - I have clarified that I am talking about MORAL rights. These are not self-evident, they are based on valid claims and appeals to ethical principles. You may think that these do not (objectively) exist, yet we both seem to act as if they do. As I mentioned before, the existence of 'objective moral truths' is discussed in philosophy. I am now keen to read some more, so I can make a better contribution.
