The biggest issue is that we have a very root and fundamental disconnect and disagreement between people who believe abortion is not murder, but a minor operation to remove an unwanted growth in their body, and a people who believe that abortion is murder, killing a soul, something that has been in existence for all time, and manifested as a human blessing from a higher power. Not something to selfishly trifle about even if the facts are that most unwanted child births would make their communities and neighborhoods and adjacent societies better because outside of the rare feel good story, they are invariably not raised by people we would call good parents who should be responsible for bringing up a child. And the costs of welfare and crime and everything else would be reduced, so there are definitely selfish reasons that are compelling to all, regardless your belief.
Once you get into spiritual and theoretical matters, you lose people who aren’t able to conceive or conceptualize beyond the literal demands in front of their nose and whose beliefs fail to launch beyond the very terrestrial limitations of observable scientific experimentations.
It’s complicated and messy and difficult because to change means to change other people’s hearts and minds. It’s not efficient, for either side.
So that leaves us very frustrated and sad, no matter which side we land on, and it divides us.
