@rahBesides, cast members are allowed opinions. Just as much as you can disbelieve it, that doesn't mean either of you are right or wrong in this case. Like I said, you can't necessary quantify the impact. But likewise, that doesn't make such claims
disingenuous. They could be simply and straightforwardly-held beliefs.
To talk a bit more about Star Wars, you included it in the same paragraph of the same post as Ghostbusters, when talking about those involved in the making of the movie who couldn't admit they made a bad movie. You said "another example would be the cast and crew of Star Wars". A mistake, then?
To talk about sexism and racism specifically, again, it definitely exists. Two of the leading actress in the middle episode were harassed off of social media. If you want to criticise the plot, or the acting, or whatever, do so. But there absolutely was an influx of criticism that was focused solely on characters that happened to be women, and / or not be white. It would be
quite the coincidence if this matched precisely with the actual faults of the movies in question.
