Reproductive rights are human rights
I'm originally from Brazil, a third-world country where abortion is illegal. This fact doesn't prevent abortions from happening at all. Everyone knows someone who did it. I'd even go as far as saying someone in every single extended family in Brazil has certainly done it, whether you know it or not.
The difference is all these procedures were clandestine and many were unsafe, unsanitary, dangerous and unnecessarily painful.
The only outcome of making abortion illegal is endangering people's lives. Full stop. You're not preventing it from happening, you're only preventing it from happening safely.
