There is no such thing as a pre-born person. Try to grow up and use correct terminology if it's under 6 weeks it's ban embryo, if it's over 6 weeks it's a fetus. If it's born it's a baby and a person. Generally it is and always has been none of your business.In a free nation the pre-born PEOPLE have much more right to be born and have life, than pregnant women have to prevent them from being born.
Generally, for the pregnant women, it is a matter of convenience. For the pre-born people, it is a matter of life & death. Just ask those thousands of adults whose mothers considered aborting them years ago, but decided to give birth.
