“Actually it is the people who support the death penalty in the US for whom that is true. “
So you are arguing with R Moshe Feinstein’s psak. Not at all surprising.
But, as usual, you are obfuscating.
Your comment above was whether we would have moral problems with the US administering the death penalty for petty theft.
Now everyone knows that the US does not administer the death penalty for petty theft. The point of your inane comment was to suppose that the US would issue the death penalty in accordance with halacha (Sheva Mitzvos Bnei Noach). And your insistence was that administering the death penalty in accordance with halacha is amoral.
Once again you attempt to twist what you said. Because the clear implication of your earlier comment was that that the administration would be in accordance with the Torah, but that is should be clear to everyone that doing so is immoral.
