The thing is, Disney is every time the one that starts the flames, years in advance, probably as a vector for what they know will be a disastrous product...

Taking the Acolyte as an example: They had the Cast make derogatory remarks about the fans and Star Wars in general ("Star Wars does not have strong women" conveniently forgot about Leia?) full years before any part of the Acolyte was finished. ... why??

They even had cast members who clearly did not know anything about Star Wars ("Anakin blew up the Death Star") proclaim their "wisdom" as stated fact. ("Star Wars has no good and evil")

Why are fans not allowed to be angry?

Fans don't care about diverse lesbian witch covens, they shrug it off, SW is filled with all kinds of aliens, it's Disney that keeps pointing it out, look! Look! Look upon our glorious lesbian witches, they are what Star Wars is now!

What we do care about is atrocious writing, writing so bad it looks like an 11 year old's fanfic, writing stuff that does not fit in the SW universe... but we need to swallow the stinking mess and smile because it is written by a lgbtq person who claims to know better than George Lucas...

$180M worth of wasted potential that may not be criticized or you'll be declared a toxic fan.

"The force is female", strange, no one declared it to be male, it never had a gender, why suddenly this gendered labeling? Quite weird that protesting against such sexist remarks is considered toxic....

Another small example, one of the high republic books from a few years ago had, in all seriousness, a chunk of inanimate rock as a "jedi navigator/pilot". And fans are not allowed to be angry about that?

Concluding, it's not the fans who are toxic, the toxicity originated each time from within Disney's Lucasfilm.
