Why not? They still have feelings, and what we feel is essentially what makes us who we are, no matter what we accomplish. Even if someone does not accomplish anything, that person is still deserves to live just as much as others, and should not be considered inferior. In my opinion, that is what respect is - to not see something as equal or appreciate something for what it is.
Of course, that doesn't mean they should necesarily be regarded as superior in any given field either. But regarded as superior to onesself or worthy to do something... that doesn't seem like respect, it seems more like *honor*.
I disagree. Animals have feelings; what distinguishes humans is their accomplishments and their capacity to satisfy the needs of another and to self sacrifice for another.
All distinctions between an animal are arbitrary and quantitative: dolphin's have 3% different DNA, who decided where the line was drawn between 3% different and 0.001% different? Why is one a whole different species and another just a different individual? Chimpanzees have more in common than me than paralysed deaf mutes, and I don't see why *** people should be treated so much better than animals.
Respecting something for what it is: monkeys are respected as monkeys and retards are respected as what they are, but I don't see why there is an issue with equating the two.

) our views are coloured by who we are, who brought us up, what we were taught by others and how we have internalised our experiences.
