[One Piece]in what sense are the straw hat crew pirates? I don’t recall them pillaging anything, and they’re actually pretty cool guys. More adventurers than anything. I don’t think they know what a pirate is.

In One Piece verse, a pirate is someone who has Jolly Roger. That specifically means that they’ve taken up arms against the government.

In the pilot chapter, there were explicitly two types of pirates: pillagers and adventurers.
