That's not true. It was arguably pretty conservative because Lucas' goal was to give young people an "honest, wholesome fantasy life" of the kind that his generation had in the 1950s, hoping that it would offer "the romance, the adventure, and the fun that used to be in practically every movie." He was reacting to all of the serious and depressing content that was prevalent in the 1970s and choosing to go against the trend. When he made his previous film, American Graffiti, he even said that current movies make us "more depressed than we were before. So I made a film where, essentially, we can get rid of some of those frustrations, the feeling that everything seems futile." He deliberately left real world problems and frustrations out of that film and seems to have carried that philosophy into Star Wars, a film that was a hopeful escape from reality. Yes, the villains were based on the Nazis and the Ewoks on the Viet-Cong, but fiction has always been inspired by real life. You shouldn't conflate that with being "woke." That's not what the term means. It means awareness of social injustice. Lucas did not use Star Wars as a platform for social injustice. Headland arguably did.
