I don't get it Kevin, and I'm seriously trying here. You see, Number 3 sounds basically like number 1, specifically the "and apply them to all entities regardless of species" part. That's basically saying that the moral treatment should apply to ALL LIVING CREATURES. In other words, what Number 1 is claiming: That Humans and Animals are identically the same.
Okay. Look, read (1) and (3) again. Can you conceive of
any circumstances in which the behaviour of someone who follows (1) would be different to the behaviour of someone who follows (3)?
Or to put it another way, can you conceive of any morally relevant criteria for moral importance, under which a mouse might score lower than a human?
If you can't, I don't know what's wrong with you but I don't think I can fix it. If you can, you should be able to work out from there what the difference between (1) and (3) is.
That was just confusing, sorry. What the hell does "being nice to animals" mean? How do you measure that? And how is that relevant? What about treating them nice while killing them? Does that count?
Once again I struggle to see how you can be having difficulty grasping this after repeated explanations.
Peter Singer would have us spend time and money to see that seriously intellectually disabled people are well-treated, and thinks they should not be killed for sport or raised in inhumane conditions for meat. Peter Singer would have us spend time and money to see that animals are well-treated, and thinks they should not be killed for sport or raised in inhumane conditions for meat. He sees the two cases as morally identical, assuming that the intellectually disabled persons in question have mental lives roughly comparable to that of a deer.
All I know is that your justification for killing some animals, such as insects, is that "they don't suffer". If your only concern about the killing of animals is their suffering, then everything should be ok as long as we kill them in a quick painless way. If I'm wrong, then surely your criteria doesn't limit itself to "it's immoral because they suffer", right? What is it then? What's your criteria for determining when it is ok to kill some living entities and when it isn't?
Suffering is a big part of the issue, certainly, and if you acknowledge that as being a significant issue then there are immediately questions to be answered about the morality of eating meat that comes from feedlots and battery farms. If you wanted to call yourself a moral being you'd be in immediate need of an answer the question of what your excuse for eating such produce was.
If you could completely eliminate suffering from the meat production process that would completely eliminate one source of moral concern.
Another source of concern is whether there are moral reasons not to end lives lightly, or for trivial reasons like taste preference. You seem to have the idea that it's
not okay to go around killing adult humans for trivial reasons as long as you do it painlessly, and it's a very popular idea to be sure. So there must be more to the moral question of life and death than just the suffering caused by killing - otherwise it would be silly to punish someone more harshly for painlessly murdering someone than you would punish them for breaking someone's arm (without anaesthetic).
Possibly relevant, depending on your point of view, is whether it's a moral use of our global luxury budget to raise animals and then kill them for meat, when there are other luxuries we could have instead that don't involve directly killing things.
And I sure hope it's not just because you like the cute ones and don't care about the ugly ones.
Interesting you should say that, because here comes Cavemonster...
Okay, here are my relevant criteria
1) The ability to react to my behavior, both positively and negatively, both in the long or short term and by doing so be a significant help or hindrance to my personal goals and safety.
2) The active protection of entities with the above quality (driven by emotional attachment or utility).
3) My visceral sympathy, by which i mean that harming them would be emotionally harmful to me.
...with some irrelevant criteria including the cuteness provision.
(1) is not morally relevant. Suppose I was a God-like being who was so powerful that humanity could not ever be a significant help or hindrance to my personal goals and safety: Does it seem immediately obvious that there is nothing to say from a moral perspective about my actions? If I tortured kids to death for fun with my God-like powers would that be a morally neutral act just because I'm really powerful?
(2) is not morally relevant. A bear might quite happily eat a human, just because it's hungry and it's a bear. Does it seem immediately obvious that there is nothing to say from a moral perspective about torturing bears?
(3) is not morally relevant. People are averse to harming cute things and less averse to harming ugly things, whether those things are humans or animals, but that is pure prejudice and not a morally relevant consideration. Ron's got that figured out, so it's not like this is a loonie vegetarian position.
