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?
