Why can't I call the fetus "a baby?

A member of the Abortion Gang wonders out loud why she shouldn't describe an unborn children as a "baby":

So what if a woman calls a fetus a baby? So what if I follow her lead and say the word baby too? I shouldn’t refrain from using words that the woman is most comfortable with. If after her abortion she feels that her baby died and became an angel, then why can’t I agree with her on that?
