I definitely agree the momo x robin and Nami panels are fucked up. I just view sanjis stuff as wrong too bc of the laws I was raised with. 18 is the Max with anyone below 18 in aus, it's a waste of your time but it's just a law that's morally engrained in me
You can keep your opinion based on your country, and its ok to keep it, having unity in a country its good, but we should not call names on others peoples beliefs, so immo dissing on Sanji in this situation is pointless.
What is certain is the stuff between nami and momonosuke, and even robin, those panels and implications are super wrong, and in no country those kind of relations will be seen normal, 20yr and 8yr kids, so yeah, this topic can pe spicy, but the implications are there, and those things are more depraved than what happens in japan-aus-globe legally.
