You are right, viability does keep moving further and further back. At some point, we will have the technology to remove the fetus from the woman and plant it in an artificial womb. Then we will all have that brave new world to contend with.
I still as of yet have to see a study that says the US is worse off because there are 40 million less people since Roe in the US than there should be. Like I said, it is the last worst choice a woman should have to make, but your side has worked its ass off to make reducing the number of unintended pregnancies harder to do. Your side, and they are YOUR SIDE, want to teach kids to just ignore that innate drive they feel to breed. Go take a cold shower, go play baseball but for god sake don't buy that condom, don't get on the pill. Don't teach kids how to NOT get pregnant because if you teach them that you are teaching them it is ok to have sex. The right has busted its ass to make this problem worse, they get all defensive of the fetus while it is in utero, but then when born it is the mothers fault she has a child she can't feed, it is the mothers fault that he child doesn't have insurance, this remarkable gift become "the mother's fault" almost at birth.
