You want to ban them because the single cell
zygote attached to the uterine wall, in your minds, is EXACTLY THE same as a breathing, functional, sentient, concious person.
Not exact matches
To put in simple terms... it does not allow a fertilized ovum (
zygote) to
attach to the uterine wall.
When this
zygote goes through more cell changes and divisions and
attaches itself to your uterus wall, your developing baby reaches the embryonic stage.
Before being
attached to the uterine wall the ovum cells divide a lot of times and it becomes a
zygote.
