I latched onto this show completely out of the blue because I saw threads of a deep social commentary and deconstruction of some really dumb anime troupes.
This is my whole point. You've gone looking for a specific message in this show because you view the entire world through the lens of far-left gender theory, and it leads you to go running up blind alleys and see patterns where they do not exist.
Have you ever heard of the book
Expert Political Judgment by Philip E. Tetlock? It's an amazing book, and one that everyone should read. It's about a large study that was conducted over the course of 20 years to test the predictive accuracy and internal logical consistency of both laypeople and experts from a wide variety of backgrounds. Everyone scored pretty badly - overall, worse than even crude algorithms - and Tetlock didn't find much correlation between score and political stripe, or even score and expert status. However, he
did find a major correlation between score and how much of a "fox" or a "hedgehog" you are, as defined by Isaiah Berlin in
his famous essay. In Tetlock's study, hedgehogs scored dismally across the board, presumably because it's pretty difficult to see things in objective and non-ideological terms when you draw so much of your worldview from one central, unifying idea.
The reason why I bring this up is that, and I mean this with no personal disrespect, you yourself are one of the biggest hedgehogs I know: you have one big thing that you care an awful lot about and spend a lot of time pontificating on - you see small, ambiguous things as manifestations of a larger theory or struggle - you see the world in highly ideological terms - and you are very deeply ensconced in a well-established school of thought. You've made some extremely bold, ideologically-motivated judgments in this thread, and now, after they've barely even been called into question, you're starting to lose your spaghetti and get conspicuously backpedally and defensive, as usual.
Yes, the show could be sending a message about rape culture and body positivity or whatever. It could also be sending one about the oppressive conformity of Japanese society, a theme that has surfaced in Imaishi's previous works and makes a lot more empirical sense given his style and personal background. It could also be that, as I already mentioned, he just likes sexy women, as well as stylish action and slapstick comedy. It could be all or none of these things. Either way, your judgments aren't rational - they clearly have a lot more to do with you than with the show itself.
Basically, all I'm asking is for you to seriously examine how your own personal political outlook might be warping your impressions here. Not just of the possible subtext, but of the show in general, such as your implication that it's "stupid trash" if it turns out to not carry the message you hoped it did. Not everything revolves around gender politics.
