As I wrote, abortion is a very responsible option. What is not responsible is having a kid you cannot afford and expecting others to pay for it. Or taking the path of least resistance...which is doing nothing and remaining pregnant...and smoking and drinking and doing drugs because you really dont care. Or it enables them to give the attention and financial resources they do have to the kids they already have and living in a more secure place.
And you are fantasizing about unborn that you are not even aware of except in the abstract manufactured to use as a bludgeon against women ...there are no millions of murdered children. THat is something that you choose to personalize and fantasize about. Great...the unfounded angst is all yours.
