Actually pro lifers can technically be called pro birth, it's not really life per se that they care about, it's only about the baby "being born at all costs," with all costs being the key phrase here.
Black and Hispanic women have abortions because they can't afford another pregnancy with working the maximum hours to care for their young ones. They also face less access to reproductive services so birthers are throwing fuel onto already societal problems that haven't been solved. Birthers are upholding a system that systematically discriminates against poor people.
Here's the facts, we know that widespread access to abortion doesn't make "more abortions occur" but less. There's actually more abortions with less access to care, have abortion illegalized doesn't make a difference in the number of abortions performed.
I'm sure white pro birthers want to do as their ancestors did pretending to be holier than thou to black and Hispanic women but it's not true, sorry.
