Beside having a soul and spirit, as is taught in Scripture, we know from modern medical science, the unborn child can feel significant physical pain down to between 6-8. Study has also been underway to docent more clearly, the development of an unborn baby’s response to emotion - fear, and hate etc...
So what this group needs to satisfy their bloodlust, is actual audio of the unborn crying out in excruciating pain, while they are having their limbs ripped off, sawn off, and drill bits and large guage needles stuck through their eyes, as is the actual practice in order to suck their brains out, or the pain in their little chest, from induced heart attacks, which is also common.
If there were actually motivated by morality that could have an effect, though they could also just argue for sedation of the infant first, or removal of the brain.
However, for most any expression of appeal to morality is simply a means to an end, that of gaining credence for their immoral goals.
