In retrospect, the wording was a bit awkard. Let me explain. Just as murdering a born child is worse than murdering an adult, murdering an unborn child is worse than murdering a born child.
This isn't an odd position. In some areas in the US, beating up a pregnant woman resulting in miscarriage is considered murdering a child under six, carrying an automatic death penalty.
Furthermore, consider the following.
Israel has been ravaged by two million abortions, while being overwhelmed by rapidly breeding Arabs.
Because Arabs use their children as stone-throwing cannon fodder, Israeli soldiers often have no other option than shooting these children.
