I think generally it’s because there was so much discourse on Era about people being reductive in their arguments surrounding this and it’s now embedded. Saying that people who don’t like the film are either must be A: Susceptible to the alt right mindset somehow or B: Just being contrarian. When we obviously know that’s not the case for many people. Then you have basically people just piling anecdotal evidence on to support their beliefs about people who do or don’t like the films.I don't know how to explain to people that you don't have to endlessly be on guard about your opinions of a movie. Agreeing that TLJ was exploited by bad actors to perpetuate a culture war does not mean that you liked TLJ as a movie. Agreeing Kelly Marie Tran went through completely undeserved bullshit for someone simply acting in a movie does not mean that you're a fan of Rose as a character.
People talk about TLJ like it's the first divisive film to ever come to existence and it's absolutely insane.
It definitely also falls under the cognitive dissonance conundrum that it’s ok to love and or support something, a property, work etc. and still be critical of it. They aren’t mutually exclusive.
