Perhaps we can come to a compromise. We can pay for women who otherwise would have had an abortion to pop their fetuses into these artificial wombs. Everyone is happy at this point I assume. Then we can all get on with our lives, charitably or otherwise. Sarcasm aside, I assume you already know that the hateful conservatives you are deriding are actually more likely to adopt children than the loving liberals you are defending.
At some point we can ask these post-birth fetuses whether they would like to continue living or if they would rather be aborted. I imagine around the age of 12 years the fetus would know whether their adopted/foster/gulag living arrangement is sufficiently pleasant to make further life worth while. If the answer is no they can be easily aborted at that stage.
