A friend of a friend is going to die soon, who could have been saved by stem cell research. This didn't happen because of "concern" over "ethical issues". Stem cell research, embryological research, and cloning have all been suppressed in the US in the name of "ethical issues".
As far as I know, there are no ethical dilemmas involved in any of these fields. Not one. What are some of the objections people make? "Human clones will be raised for body parts!" - We already have laws against murder. "Clones would have no individuality! / no soul!" Tell that to an identical twin. "Embryos / micro-Americans are being killed for this research!" No; they've already been killed. As long as abortion is legal, there is a limitless supply of already-disposed-of embryos for research. If you have issues with that, take it up with Roe vs. Wade, not with the NIH. And, "But some madman might clone Hitler!"
That's why we should clone Hitler as soon as possible. I don't know if there are any clonable Hitler fragments preserved somewhere - a fingernail, a lock of hair, whatever - but if so, we should clone him. Just to get it over with. Then we can say, "Look, we cloned Hitler, and nothing bad happened. And that was your worst-case scenario."
