The literal and legal definitions of murder prevent any abortion from being called murder. The only people who call it murder are pro-lifers who wish it was unconstitutional. They want to believe it is murder when, at least in the United States, that is constitutionally impossible, to push their anti-choice narrative.
If fetuses were people, they would be counted on the U.S. Census every 10 years. They would be labeled U.S. citizens. Birthdays would mean nothing. The 14th Amendment could not be more clear: only persons "born or naturalized" can be citizens of the United States and have the rights to life, liberty, and property.
Of course, I am not saying churches should stop condemning abortion. I am just explaining what is wrong with the way they do it - calling people murderers, baby killers, etc. Wanting to lock up women instead of, as Jesus often taught, helping them with love and kindness. What happened to, "Do unto others what you would have them do unto you," a sentence straight out of the Lord's mouth? When used by all churches to condemn abortion, the word murder is both completely false and completely misogynistic.
