Not really. You just arbitrarily decided it is so. If I showed you both pig and human fertilized eggs, you would not know the difference.
That does not change anything. Yes you cannot visually distinguish a human embryo from an animal one but so what one is a human at the beginning of its life the other is an animal. Why do you seek to dehumanize a substantial portion of your fellow human beings?
Earlier you stated this was your moral code?
- if the action causes harm, it is immoral
I am curious how you decided that killing someone does not count as harming them? Or is your stated moral code only for show something that rolls easily off of the tongue but is designed to be casually set aside when it becomes inconvenient?
Easy. A fertilized egg is not "someone". Once you get the CNS working, then you can talk about a human being. Until then is just a bunch of cells. Just like a poured foundation is not a house. Seed in the ground is not a plant.
The fertilized egg does not feel, the nervous system is not there.
I am not trying to dehumanize human beings. A fertilized egg is not a human being.
Maybe you should start with the definition of a human being before you accuse me of harming human beings.
If you think a fertilized egg is a human being, you are simply mistaken because a human being is way more complicated.
PS. Working with fertilized eggs and extracting stem cells in the process is not causing harm, it is helping people.
