Warbler said: nope, its only sacred when the sperm and ovum have combined to make an embryo.
Whatever you say, every sperm and ovum is potentially sacred then, it doesn't really change the point I was making.
Adolf Hitler was a fertilised ovum once. That's the problem with the process. you don't know what you will end up with.
Warbler said : sorry, not getting how attaching more value to a developed human fetus than to some other animal is just sentimental.
An animal that has been alive for a reasonably long time has a connection to it's, world, it's own life and to the lives of others of it's species.
If it is lucky it has connections to members of other species too.
It is aware of life and aware of pain and can conceptualise having either taken away.
It is capable of suffering in a way that is in advance of a human fetus which responds to the stimulation of pain but has no context to place that stimulation into.
The fetus can't imagine a situation without pain and struggle towards it.
It can not suffer.
Therefore any value we place on it (other than genetic investment if it is a family member) is based purely on it's likeness to us rather than any qualities it would have outside that of any other animal.
Which is the very definition of sentimentality.
It's why people want to protect Pandas over alien looking insects.
