No, that's the shitty excuse Disney executives like to hide behind. "PEOPLE ARE JUST MAD WE FEATURED A WOMAN/BLACK PERSON/GAY COUPLE!"

No, people are mad because your writing is shit. Most people are actually A-OK with minority characters, as long as you give them a reason to like the characters. (Except China, but Disney knew that so they made sure they didn't feature the problematic black character over there). Make them interesting, don't make them a Mary Sue, don't build their plot up only to yank it away at the last second and turn them into just another background character.

But no, Disney can't do that because they are terrified of trying new things. So they made the blandest, most milquetoast, characters possible and made the plot Baby's-First-Starwars in the first sequel, took what the fans loved about Star Wars and literally burnt it in front of them in the second sequel (while telling fans they were stupid to ever like that part of Star Wars in the first place), and then backtracked HARD into Baby's-First-Starwars again in the third sequel when they were shocked to discover that fans didn't like being insulted.

So many issues with the sequels, complete corporate ignorance to just chalk it up to a "toxic fandom".
