Vegitarians consider animal life to be every bit as sacred as you do fetal life. The logic behind dinner-table-animal slaughter images and choped up fetal images are exactly the same for the vegitarian and you. That logic being "if they see the horror, they will change their minds."
You do not believe the lives of animals to be worth converting to vagitarianism. Those images would make no difference to you.
The people who believe that fetuses are not real person will like wise no be converted by the images.
(My apologies to any vegitarians for using this example. I have never known a vegitarian to demand another person not eat meat.)
