Thanks for the great comment! I'm a bit more on the applied side of things (social sciences), so I consider that (application) more than things philosophers consider, which you have outlined in your comment. My approach is more concerned with how people view, act on, and use morality, which is why my comment reads the way it does. I will read Nietzsche sometime, I've heard good things :) Again, thank you for taking out the time to write a play-by-play explanation/rebuttal!
I'm glad I could help! But there's no need to thank you; I just like sharing knowledge with others about things I'm passionate about. When you have a chance read this page on Egoism. It has to do with psychology of actions so it's a perfect fit. Let me know if you have any other questions in the future and I would be glad to help with what I can.
