When I said to raise a child, it meant to give it love, nourishment, attention, and care. Everyone goes through suffering, but it is the parent's responsibility to try to reduce the suffering.
Non-chemically altered cells are different from chemically altered cells. Why would I consider the death of both to be the same thing, when one has potential to become a human and the other has NO potential to become a human?
Ok, just because someone shits out a baby, and you tell them they need to "raise" it (in your sense of the word),
they might not actually do that. Did you know that? People, as a whole, are actually really awful. Even well meaning parents can completely ruin their children - utterly indifferent, or maybe even resentful, ones can do damage that would take more than a lifetime of therapy to undo. It's nice that you think parenthood automatically instills perfect values and childcare qualifications, but this is the real world, not La La Loopsy Land.
As to the second paragraph. Let me lay it out for you one more time:
1) Small groups of cells, no matter their origin, cannot grow into a human on their own.
2) To grow into a human, cells need outside help.
3) This can be provided by a mother, such as in the case of a natural pregnancy.
4) This can also be provided by scientists in a laboratory, such as in the case of early IVF therapy.
5) The differences between (3) and (4) are not important.
6) The take home message is that cells can
only grow into a human on their own with outside help. See (1) and (2) for details.
7)
Therefore, if killing cells of type (3) is murder, then
so must be killing cells of type (4).
8) The catch is that
all cells are of type (4).
9) Describing the killing of
any human cell as murder, while consistent with your proposition, is ludicrous.
10) Ergo, your proposition is similarly ludicrous.
