I don’t disagree with the point about distinguishing between one being more worth of love but individuality is really only existent because of group thought. Everything you have ever learned was a linguistic depiction of reality or events told by someone else. There is one human knowledge that is constantly growing that you can choose to learn from and eventually build up on if you focus on a field of study and make some discovery. I believe in subjective morality and that it is ultimately learned unless genetic conditions. Although it’s utterly impossible to have a definitive answer on morality at all in my opinion
