Ok to be clear, I am 100% certain you don’t know what virtue ethics is because you’re literally describing principles of action not virtues. Virtues in virtues ethics are dispositions we cultivate in ourselves not in the consequence of the world. So taking your example of the “principle of impartiality” is that if you are a virtue ethicist you’re trying to cultivate “impartiality” not duty bound by it. This is also why you’re confused when you name virtues because independence is a virtue in the person receiving aid not in you! Also these are canonically not virtues any well-known virtue ethicist would name!
Moreover, this impartiality is more a metaethical principle that you keep violating in your own examples. If Oxfam trades off 2:1 Bangladeshis to South Sudanese (replace the countries with whatever you want) that breaks impartiality because you are necessarily saying one life is worth more than another (there are morally particular facts that can change this obviously but you keep biting the bullet on any and just say the world is fuzzy!)
Overall, the world is fuzzy but the problem in this chain of logic is your fuzziness in understanding of what commonly used concepts like virtue ethics are. It’s really frustrating when you keep excusing your mistaken understanding of concepts with the world being fuzzy. Please just go read Alastair McIntyre’s After Virtue.
This is not how words work. You can’t just say I believe X is a virtue because in humanitarian ethics (which is ill-defined). I truly don’t think you understand the concept of virtue ethics at the end of the day. This sounds mean by it’s definitionally a misunderstanding you keep doubling down on like everything here. For instance you tried to use the red cross as an example but most virtue ethicists wouldn’t abide by an entity holding a virtue (the ICRC can’t cultivate a virtue it’s not a person) -- because that’s definitionally not what a virtue is. You also misquoted Alasdair McIntyre and misrepresented it as shown by the fact your quoting all come from google book snippets from undergraduate classes.
I think you believe what you believe and I’ll leave it at that. This is not a productive conversation. Funnily enough I do not think the paper draft is charitable but I don’t think you fully understand your axiomatic values (you probably are prioritarian not a virtue ethicist). I also think the educating girls example is a very strong prioritarian argument.
