We have tons of studies to prove it.
You can look at American history pre-Roe or, more recently, to Brazil: nytimes.com/2018/05/31/opi…
They view abortion and access to abortion as being about women having the right to bodily autonomy.
They see that as foundational to every other type of freedom, right, Independence and equality for women.
I just don’t see how making abortion illegal will prevent abortions.
I’d encourage folks with that view to advocate for comprehensive sex ed, free birth control and a stronger safety net.
Also, from years of failed abstinence only education we know it does NOT work.
