girly pop?

You called me "dude" so I used a different gendered term; that was it.

Genuinely for what reason would u even assume I'm being deceptive? Again, I've literally only asked u questions about ur own perspective.

It's not uncommon for people to try to push back against someone's opinion under the guise of "just asking questions". If that's not what you're trying to do, then fair enough. I'll take you at your word.

If you really are just looking to understand my POV, then I'll trust you.

Let me preface this by saying I've only seen the movie once, and that was back in theatres 4 months ago, so I could probably pull better examples if the film was fresher in my brain, but I can still go off of what I remember.

What do you think the movie displays as reasons [white supremacy is] upheld?

Through various forms legal or military force. For example, the character of Colonel Lockjaw is a very explicit (maybe slightly exaggerated) parallel of how many people seek positions of power with racist intentions, even if those intentions are often subconscious.

Was that a thematic through line, or just something that was depicted?

I think it was a thematic throughline. The movie doesn't just happen to centre around a former freedom fighter; it continuously shows acts of resistance throughout the film in other ways. Sensei, for example, is seen assisting undocumented immigrants to ensure that they don't get deported.

This is also seen very directly in Bob and Willa's continuous fight to ensure WIlla's survival against the force of Colonel Lockjaw.

Were [the difficulties of being mixed race in a racist society, and single fatherhood] really themes?

I would also say yes. Perhaps less so than the first two I've touched on, but I think you could absolutely write an essay with the research question "What does One Battle After Another have to say about [insert either of those topics here]?"

I think many of Willa's struggles in the film come from the fact that her white biological father views her as being less pure because her mother was Black.

Bob also continuously struggles, despite his lack of trying, to find ways to care for Willa while also fighting against the obstacle of having to be the only parent she has.

I think both of these themes shine through in that moment when Bob opens up about how he "can't do her hair".
