But that's the problem. In the example you used with the car, getting pregnant doesn't correspond to "buying" the car. It can correspond to taking the car for a test drive. Cars aside, abortion isn't just a moral or physical decision but a socio-economic one, and a majorly political one too. You don't hear countries with overwhelming population perpetuating the "abortion is a murder" agenda. No everyone can afford to have a kid, and some people are simply horrible humans and even worse parents. For some, having that child would mean destroying its life. Which is why access to abortion is crucial.

People who have been brainwashed into the "abortion is murder" belief often reside in religious countries, which is a problem of its own because religion has probably done more harm than good worldwide.
