Last point before I go.
Oda showed that Wano is a bad country.
Oda told that Wano is a good country through Wanonese people.
Conclusion: Wanonese are overly patriotic people who are fed propaganda and fail to see their flaws (just like pre WW2 Japan)
One of the best examples of show, not tell. Even Wanonese people's ignorance is shown through them telling "Wano is a good country".
If you thought Oda was trying to tell Wano was in a good situation because the characters verbalize these things, you missed the point.
Kids here need to be spoonfed. Showing without telling is harder for them to understand.
Reason I wrote in this format? Reading a whole paragraph might be hard for some people here.
