That is not what I asked. Let me try again.
Is a fertilized egg a human, like you and me, or the children that were experimented on by the Nazis?
When do you consider an embryo to be a person?
Your very question highlights your bias.
You are attempting to seperate humanity into two groups the ones who you feel are the real humans which you are calling persons deserving of human rights and others whom you presumably feel can be owned, sold, killed, or experimented upon as one would a lifeless object.
Its a common error. Slavers have used it throughout history to justify the kidnapping and enslavement of the weak. Nazis used it to to justify mass starvation of the inferior Russians. We use it today to justify the killing of the unborn.
There is no person catagory. There are just human beings at various stages of growth and development young and old.
