영어 지문이 잘 해석되지 않아 도움 부탁드려요.
“No one objects to destroying a sperm cell or an egg cell. A newly fertilized ovum (an embryo) is nothing but two such cells, and it would be irrational to object to disposing of it. An embryo on the second day after formation is barely different than on the first day. And as time passes, there is little difference from one day to the next. There is no natural stopping place and no grounds for objecting to abortion at any stage. If two cells are not a person and an embryo is not a person, there is no person before birth occurs. Murder involves killing a person, so abortion is not murder.”
