If you’re the only true follower of the philosophy you promote, if you are the only person who is true to the spirit of your morally better culture, if others are treating you wrong but you treat them right, then you are the better person.
However, what if that philosophy of yours is hindering you while achieving your goals? What if your morally better culture is closed and looks down upon people who behave differently, scaring them away? What if your right is the wrong in someone else’s eyes and there is no way to prove that wrong objectively?
Doesn’t your moral perfection, your superiority to all those inferior hypocrites make it harder to enjoy what you like to do, to reach the people you want to reach, to have success where you want to succeed? Doesn’t that make your moral perfection useless? Doesn’t it mean that those people with their flawed human nature might be achieving more with their sensible, flexible, pragmatic approach?
