“Can you please stop killing a foetus a child?”
I think it is very telling that you made this ‘error’. I think your heart is trying to tell you something, and I agree. Can you please stop killing a foetus?
Here is the actual definition of child:
noun, plural children
a person between birth and full growth; a boy or girl:
books for children.
a son or daughter:
All my children are married.
a baby or infant.
a human fetus.
a childish person:
He’s such a child about money.
a child of an ancient breed.
any person or thing regarded as the product or result of particular agencies, influences, etc.:
Abstract art is a child of the 20th century.
You can’t pick the one definition of a word that fits your agenda. Most people with a moral compass use the word baby and child synonymously when referring to preborn human beings. The real question here is why does it bother you so much? Maybe because it humanizes the very human beings you want so badly to have the right to kill?
