Appreciate the honest and (somewhat) applicable answer!
I also DO NOT appreciate the downvotes … we really need to get rid of those. Don’t agree, fine, move on or respond civilly. A downvote is a manifestly uncivil action sanctioned by the interface.
Otherwise … to respond to the abortion argument … where this falls down for me is the complete lack of any mention of the mother or woman in your reasoning.
Scientifically, this challenges the “humanness” of a foetus in the way it is tightly coupled and dependent on another human to live. Morally, it raises much of your reasoning in relation to not fucking with people once you consider what is effectively done to women by forcing them to carry any foetus to birth which is a massive, very active and obviously risky undertaking.
Whether these are convincing for you or others, the lack of any weight given for these considerations indicates that the act of birthing is presumed as a duty of all women. A presumption that IMO undermines the completeness of your scientific and moral arguments.
To take that a little further … should people be legally compelled to secure and save the lives of babies? As it is now, that’s not the case anywhere I know of. Causing harm would be criminal, obviously, but failing to save a baby or anyone else from harm is not.
In debating the legality of abortion you enter into similar territory. Only by presuming birth as a duty can you think otherwise.
While aborting a foetus is a positive act, there’s the complication that it’s purpose is to avoid the onus of pregnancy and birth, which can be easily seen as tantamount to “simply not doing the thing that would save the foetus’s like”, ie all the work of pregnancy and birth which is probably all too easily presumed by men (which I’m guessing you are) as a more passive and natural event than an act of effort, toil and cost.
