Give the man a cigar! Finally someone gets the point.
From zygote, to infant, to adult, to gamete, to zygote, to infant, to adult. On and on so it goes. The point of demarcation is arbitrary. It is human, it is life, it is human life, it is individual human lives. Point made. Point accepted. Argument is valid with sperm as well as with zygote or adult. All the fervor is about when it should enjoy the protections of law. When, it is, not what it is.
Mental gymnastics and not very convincing ones at that. A zygote has a unique DNA structure that has a natural drive to develop, including to develop the gametes. The gamete does not have a unique DNA structure that has a natural drive to develop.
An infant is not a seperation from a zygote, nor is an adult, they are stages of development from the same zygote. To equate the gamete as a period of development after the adult stage is to claim that an adult develops into a skin cell, or a white blood cell. The adult human does not develop into the adult gamete, is produces the gamete.
Zygote (human) -> Infant (human) -> Adult (human) -> White Blood cell (human)
Is that really how you view the circle of life?
Sorry, again a horrid logical argument.
By the way, you still haven't answered my very simple questions.
I'm sure you're kidding, right? A sperm is maybe HALF human, but it's not a human life.
