This is stunningly nonresponsive to the issue and is, regrettably, par for the course in these discussions.
We're Catholics. We like medicine. Flu shots are wonderful things! We like killing people a lot less. In vitro fertilization requires the creation and destruction of many, many embryos. Well over seven per attempt, when everything goes right, although the denominator is not really relevant to our reasons for disliking it.
The debate on whether an embryo is a person or not (in the moral personhood sense) is not an open-and-shut question of "science", and if a little humility about the limitations of knowledge is appropriate, it is probably also appropriate for those whose advocacies necessitate the destruction of life.
If flu shots required stabbing an African in the belly to produce, Catholic moral doctrine concentrates more on the immorality of stabbing the African in the belly and less on the exact flu-shots-per-African ratio (or Africans-per-flu-shots ratio).
One of the greatest tragedies of our time is happening right now in Africa, and if it was up to the Catholic church it would be a lot bigger than it is already
Nobody has ever died due to an overly strict adherence to Catholic teaching about sexual morality. Really, think about it.
Then go the next step: if blaming the Catholic church for deaths in Africa for opposing condoms is logically sane, then it must also be the case that condoning sex outside of marriage kills Africans. Which, I rush to mention, is inane.
