What part of my argument is "no soup"? Or can't you be honest about the parallels vis-a-vis organ donation?
There is a correlation between the use of blood products and donated organs from cadavers and the use of transplants from anencephalic living donors, embryos, fetuses and prisoners. In all cases, non-autologous tissue from one human is transfused or transplanted in another.
However, the difference is exactly one of *ethics.*
In the case of cadaver donors of organs, voluntary donation of paired organs, skin, bone marrow and blood products from living donors, the donation does not require discrimination between the inalienable human rights of life and liberty of one human being and another.
You slurred, "Or can't you be honest about the parallels vis-a-vis organ donation?" It would appear that you do not see a difference in willing organ donation, willing blood banking, and taking the life of an alive individual in order to obtain organs and blood or blood products. Those are crucial distinctions if the ethics are to be discussed. Others on this thread have answered your queries most adequately, so I won't bother further.
