The answer, Alex, is they can't use a fetus as a prop to advance their political agenda. That's what it's really all about, usefulness. Liberals are all about their march towards a utopian socialist democracy. Anything that helps accomplish the total government control necessary is judged useful. So despite their feigned outrage liberals are ecstatic when a gun-free zone acts as a magnet to a lunatic and 20 children are sacrificed on the altar of Progressivism. It helps advance their agenda so it is therefore useful. For the children? Ha!
