“None of the above”, especially since there are more choices than “A”, “B” or “C”. (Even if there weren’t, one could still vote differently by write-in.)
If nothing else, it should be noted that A, the only choice which includes “pro-life”, should probably be changed to read “Anti-Abortion”, since “Anti-Stem Cell research”, and “Pro-Iraq War”, are not necessarily “pro-life”.
The papal “Declaration on the Production & the Scientific & Therapeutic Use of Human Embryonic Stem Cells” notes that “Methods for obtaining them are still being studied”, which allows that there may be methods that do not end in the destruction of human life. One of those possible methods is by obtaining them from embryos that have already died of natural causes, like miscarriage. Others are obtaining them from amniotic fluid or umbilical cord blood, neither of which require the destruction of life either.
As such, embryonic stem cell research is possible without violating Church teaching. Whether embryonic stem cell research is even worth the trouble or effort, given it’s poor to non-existent success, is probably another issue. Personally, I don’t see a need to keep pursuing ESCR, since it has been relatively unfruitful, compared to other research methods which have seen success.
