The film wasn't subtle. If you couldn't detect radical feminism within the film, that's because you're not familiar with it. It's not about the presence of women, or the number of women in the film. It's about the way men and women interacted in the film, the consequences of the characters' actions, and the normative values that were explicitly stated by the characters.
If you don't see it, you don't see it. I won't try to convince you.
Variety sums it up,
"The film’s progressive ideology is already ticking off some calcified corners of the fandom—the kind of fans who dismissed Ridley’s heroic Rey as a too-powerful “Mary Sue” after the last film. But just because some Star Wars lovers are out of reach for the message this movie delivers, there is still hope for a new generation. Just like that kid at the end of The Last Jedi, holding his broom aloft and wearing the resistance jewelry left behind by Rose, an entire generation of young Star Wars watchers will remember the brave, smart, capable women of The Last Jedi—and the consequences of doubting their leadership".
Don't question authority, because
feminism.
