I don't really think "it's just a drawing" is a defense I'm willing to take. We need more nuance in these discussions, not a complete lack of it.

Nuance is for us, not for moderators. Moderators need clear and specific guidelines that are universally enforceable, so that their hands remain completely judgment-free and their opinions have no weight. You and I, we engage with nuance to decide how we spend our time and who we spend it with.
