You may or may not be aware but because of two crucial pre-production events, the film underwent a lot of changes at an accelerated development speed. •Carrie Fisher passed away suddenly •The director originally hired for the movie shot his career in the foot and had to be let go When this happened, Luasfilm then needed to hire a new director that could also complete the writing process for the story. J.J. Abrams was brought back on and it was a fairly logical choice considering his history with Lucasfilm and Star Wars. Disney then made the call to keep the production schedule of the movie intact (arguably a very dumb decision) instead of letting Lucasfilm have a proper amount of time to make The Rise Of Skywalker. What's this all mean? It means you have J.J. Abrams and Chris Terrio rushing to make a film work. According to Terrio, parts of the movie needed to be changed due to not being able to get Leia related special effects to the finish line/a certain level of quality. These movies DO involve risk, as most Star Wars special effects have for some time now. It's not ridiculous that you have an ambitious idea for a movie but it can't be made to work in the time that you have. Ultimately, they decided to have Rose's character support the resistance and Leia at their home base, and those parts of the film were trimmed down. You are asserting that they were trimmed down because Abrams or Terrio felt the need to act on discrimination or prejudice against asian people. Her role in the film was cut because they chose to focus on the core trio of characters (Rey, Finn, and Poe) in an already bloated and overstuffed film. Choices were made because they felt it would benefit the film, and sometimes this is just part of the creative process. I think it's also worth noting that the main trio of heroes in the trilogy are 2/3 minorities.
