I think it is a no-brainer why anyone might want to terminate a pregnancy because of birth defects or some kind of illness on the part of the fetus or mother.
But for some of those who implied it’s the woman’s fault for being irresponsible and having unprotected sex, that’s rather one sided. It takes two to make babies, a man and a woman.
So why not blame the man as well for making a woman pregnant? Whether through unprotected sex or rape. Why not sterilize a man, or better yet castrate him, if he caused an unwanted pregnancies? Afterall, if a woman is condemned to look after a child, the man should also be condemned to a life of never impregnating any woman ever again.
