The same applies to stem cell research.
> How are they harmful?
Because it doesn't stop there.
It starts by banning abortion or restricting to some line (heartbeat, 4 weeks, etc..).
Doing abortion then turns into murder, and is charged by the state as such.
As the radicals (this belief is primarily christian) get more entrenched, then this window slides further into conception=life

Having this belief takes away women's agency of their own bodies. It turns them into second class citizens by making their body worth less than the similar male, solely that they can have a baby.
What's closest to being "correct" is "generally agreed to be good at guiding human behaviour into a direction that may, just possibly, survive the harsh light of passing time without being viewed as crass injustice. Or, you know, wiping out humanity (both senses of the word)".
