tzippi-excellent question which brings home the point that this issue is not so black and white. I really don’t know the answers to the specific questions that arrise, just the premise of the gemorra-i.e.men are commanded in more mitzvos etc….It could also lead to the question of two men are drowning one is a kohein and one is a yisroel etc…..
I don’t think it’s advisable for anyone to portray it as totally black and white.
