What the hell is going on with people claiming suicide is immoral? What kind of rationale are these votes based on? This is utterly ridiculous.
I'd agree with you, but why do you think cloning humans (assuming no deformities or experimentation) is inherently immoral?
Maybe it's not inherently immoral, but at the very least would raise a good number of very uncomfortable issues regarding personal identity, human rights, and eugenics, and could easily devolve into something very immoral.
I, for one, feel more or less the same way about suicide raising uncomfortable issues regarding responsibility to and for other people, although I tend to agree with DemPGH that moralizing the issue overmuch really is unhelpful.
