I enjoyed the podcast and also noticed some feminist / social marxist themes in the movie that Stefan didn't mention, possibly because they were more overt than some of the themes he touched on.
Unless I'm mistaken, everyone in the First Order was white and male. So you have the white male villains oppressing the multiracial rebellion and the rebels have a predominantly white female leadership. As Stefan has mentioned in a previous podcast, Rey bests or matches Kylo Ren in every encounter despite her total lack of training and his years of training with Luke Skywalker and Lord Snoke because she's a girl and apparently women are better than men at everything, even when lacking training and expertise. So we have the theme of the oppressed multiracial minority rebels who must be saved from the white male First Order by the white females (Rey, Leia, and Vice Admiral Holdo). In addition, Luke Skywalker, who was the hero protagonist in the early films, has proven once again that white males can't be trusted even when they start out with the best of intentions. It was also interesting that Luke, the straight white male, had to be sacrificed in order for the multiracial rebels to survive. Not only did he have to sacrifice himself to atone for his sins, but he was finally at peace after doing so. Straight, white males are called upon to fall on their sword to redeem themselves for all the evil they have perpetrated against minorities and women by virtue of their straight, white maleness, and one would surmise, their toxic masculinity. Only then will everyone, including the straight white males, be at peace.
Hope I didn't ramble on too long.
