I mean a young rape victim from a low-income area where abortion is not easily accessible and without a good family support system is likely going to be scared and confused and go for weeks carrying the child without proper information regarding what exactly she needs to do. All the while trying to deal with the mental scars and eventually overcoming the obstacles only to find that it took her 21 weeks to do so and now no longer stick to her decision.
It's easy to picture this as overly specific or something; but honestly a huge portion of the US lives in low-income areas where abortion is not easily accessible. So many American youth DON'T have a nice stable 'nuclear family' they can easily turn to. And these same people live in areas with higher crime rates: including rape. It's really not hard at all to picture a situation where a rape victim in this situation is distraught and doesn't see the signs of pregnancy until three months in: then spends the next couple months afraid to tell anyone, trying to think of ways to pay for it, not even knowing where a clinic is (and then have it not be local or anywhere close to her due to the restrictions already in place across the US), not having her own car, etc... It all can pile up.
So yeah, that's why I oppose restrictions of 20 weeks for rape victims to get an abortion.
Given the value of the growing life, and that I don't believe abortion can ultimately be psychologically therapeutic, I disagree strongly with your conclusion. However, it is nice to see someone take the effort to explain this position.
