One Piece's Monkey D. Luffy, is better defined by his actions and basic philosophies than his words, but he still has some poignant things to say. Aside from embracing the familiar power of found families and having strong themes of personal freedoms, Luffy also practices tough love. It's on-theme for someone like him, and it sets a good example in the overall shonen demographic, too.
