so you can't quote where i said that, those are memes. now answer my second question
none because i'm not directly responsible for what's killing them, i'm just doing nothing and am pro mothers doing the same, if you choose to do nothing instead of abortion then no one gets murdered lol
same goes for your kidney scenario, if x stabs y who now needs a kidney to survive, then x is responsible and is a murderer if z doesn't donate his kidney, if you stabbed y then in this case imo you are morally obligated to donate him your kidney and will be the one responsible in case he dies. of course these analogies are irrelevant to abortion for several reasons, one of which is the abortionist committing murder while the human not donating blood/kidney is not murdering or even killing, in fact that human is unrelated to the cause of death, another is the fact abortion results in the death of your own child, not just a stranger you don't know.
if parents don't feed their newborn which dies as a result, are they responsible for the death? are they obligated to feed the newborn? why? are you obligated to feed their newborn in the exact same capacity as the parents? i'll answer adjl in a few days i'm unwillingly being forced to touch grass
