Certainly not. Of course, we do do some things that I suppose some might consider the beginnings of a slippery slope in that direction, but the difference is huge if you ask me. I've heard of some cases of couples having children with certain characteristics that'd allow them to become a donor for an otherwise incurable sibling, but while I can see how that might cause psychological issues at some point down the line, they're still children who are very much wanted and treated just like the others.

The other thing is the use of stem cells, but again, really not at all like the cloning-for-organs thing.

If science ever gets around to human cloning - which does seem plausible - we will definitely run into moral problems, but I don't really see it happening that they'd be treated any different from "normal" humans. Fortunately.

I'd like to think our societies are better than that... that we would emphatically reject the idea of using humans as, well, cattle really. Of course, if it did happen, one can see how people would start seeing them as second class citizens, and who knows where that would lead... scary thought.
