See, I took the metaphor as: don't get irked by every event (boat bump) that affects you if you don't understand where it came from. Don't assume a human is controlling it when it could be an accident if you would just open your eyes and investigate. In this case I was assuming that maybe the pastor had atoned for his past by donating to or starting a charity or something.
So this interpretation of the empty boat being a metaphor for people in general is fine. It's an exercise in an aspect of stoicism (don't worry about people you can't control, you don't know what someone has been through etc.)
But to extend it to moral subjectivity is bizarre. I think you hide behind metaphor but the clear implications in the context of this discussion is that a closeted gay pastor who abused children can't be held morally accountable for their past because they had too many bad days in their childhood. What it boils down to is a platitude (I.e. that almost everyone is a good person in their own personal story), but the guy harmed other human beings.
I hope I don't have to spell out why it's heinous to imagine a world where everyone walks around not judging actions because they think all morality is subjective. It gives license to atrocious behavior.
