So, the OP pretty much established that as far as Proglodytes are concerned, you can slaughter viable infants in mid-natural birth with legal impunity so long as the entire body has not slipped free (or perhaps they'll claim the placenta as well, who knows when convenience governs all). As far as they are concerned you can kill this person because they unilaterally decree personhood is based wholly on what space one occupies and that pass is the compressed length of a vaginal canal.
And yet, here we are, harvesting every day, the various lectures, tirades and rants of the Proglodytes concerning our supposed duty to create social welfare hammocks safety nets, education, infrastructure, health care and green energy (and apparently a world with robot butlers if Juan Cole is to be believed). When you complain that they're greedy little leeches they will protest that it is not for themselves they work but only for future generations that they aspire.
If a viable child can be killed with the claim that anything less is tyranny against the adult who would presumably care for it then is this not some tyranny against the present generation by the demands of future generations? They will kill humans in the womb but they would make us slaves of those that won't be conceived for generations yet to come.
Does this make sense to anyone or are we witnessing just one more Proglodyte rage-fueled rant to impose their desires on those who prefer to keep to themselves? Doesn't all their smarmy appeals to "the world we leave to future generations" ring hollow?
