No, people don't actually inherit the attributes of their surrounding population. Controversial as it may sound, people have only the attributes that they actually have. Seems to me that, from your own example, a severely mentally retarded human or infant is no better or worse off non-rational humans.
I really have to agree with Cain on this one: the rationalization to fit humans who are "inherently incapable" of rationality into your framework requires some pretty heavy mental gymnastics. I hope I'm not the only one who doesn't buy it. It seems you could do two things here, both of which fit nicely into your ethical system: you could deny that mentally retarded humans have rights which, or you could conclude that organisms inherently incapable of rationality do have rights for other reasons (maybe cause they can suffer, and that much alone is worth considering). You may find the first option unappealing because its obviously repugnant, and the second option unappealing because its inclusive to animal rights. Pick your poison.
Addressing this last point again and also your edit.
I find it amazing that you think that my system both requires mental gymnastics to operate or that it could result in the stripping of rights from a mentally retarded person.
In terms of right to life and associated rights, in my framework
all humans have the same rights to life, freedom from abuse and freedom from torture etc.
All humans are classed as being
equal in my framework. Humans as a set are the most intelligent, rational and able species on the planet. Because we are the only species sufficiently able cognitively to grant rights, we should apply them across the board within our species. As repugnant as the idea of different species having different levels of rights might seem to you, I assure you that when it comes to the rights to life and freedom from abuses, I believe that across each level, the rights should be applied equally. I see no reason why a particularly stupid dog should be given any less of a right to life than a particularly intelligent one, but at the same time, I don't see a problem with an animal on the "level" of the dog being eaten.
Yes, I did just say I have no problems eating dog. I have not done so, and have no pressing desire to go and try some, but I might do if I were given the option.
In terms of the idea of animal rights being "poison", figure of speech or not to me, I assure you that I am a supporter of animal rights. I believe that cruelty to animals is a serious offence and should be punished far more severely than it is now, but that doesn't stop me from thinking that humans as a species are in many ways intellectually and ethically superior to other animals.
Again, I think that
as a species humans are higher up than cows, even if you conclude that a seriously low functioning human is on the same level as a cow. Call it naturalistic, call it tribalistic, call it whatever you want, but do not assume or imply that I think all human
behaviours are the same.
I was hoping for a spirited but open and friendly discussion with you, because despite what you may think of me, I have a lot of respect for you as a poster and I have a lot of respect for your opinions, even those I disagree with. I am more than willing to change my opinions on nigh on every topic, and you can rest assured that even though I eat meat, I do my best to see that what I purchase and consume is ethically reared. However, I have been somewhat disappointed with what I perceive as a hostile and condescending tone in your reply to me. Even if you disagree with my opinions, and even if I was saying what you think I was, I do not feel the attitude that I read was necessary. If I have misconstrued your attitudes, implications or meanings, or have been uncivil, aggressive, condescending or hostile to you I apologise, as I do not mean to be.
