A lot to unpack here ...
1) Winning an "Academy Award" does not mean a performer or a film is well known to the non Hollywood set. Most people really don't care about Hollywood's internal accolade tv special. A lot of the comic book fans (ie MCU customer base) on the internet didn't even know who she was until she was named to the role. Do a cursory search if you don't believe me.
2)
2a. 40% of comic book readers are female. [

2b. Since 2006, on average, 55% of video gamers are male [

2c. Female viewership of Star Wars movies has never exceeded 33%. Yet, Disney went all in SJW with the latest trilogy and have lost billions on female focused merchandising that no one asked for or wanted. [

3) Here's what she said
"[Audiences] are not allowed enough chances to read public discourse on these films by the people that the films were made for. I do not need a 40-year-old white dude to tell me what didn't work for him about
A Wrinkle in Time. It wasn't made for him. I want to know what it meant to women of color, to biracial women, to teen women of color, to teens that are biracial," she said.
"And for the third time, I do not hate white dudes, they are just facts, they are not my feelings," she added
There's nothing wrong with her thinking that or even communicating that opinion. However, there's a way of saying things to your customer base without coming off like a feminazi.
4) No, I didn't wake up one morning saying, "You know what would be cool? A "female-led" Marvel movie!". Know why? I don't care about gender, race, etc as long as the story is good. They could put a hermaphrodite as the lead character and I'd support the film if it had a good story. Pandering to toxic feminist propaganda while stepping on men isn't the way to win the other 60% of Marvel consumers. For decades, I've supported female-led comics, including Captain Marvel, and other female led movies ... a list too long to provide here. Put clearly, men, as the primary customer base of these products, dont want to be told they're the enemy to female-led films.
5) "As a white male I am floored at how sensitive my kind can be!" I'm not white. LOL
TL; DR
Real, hard cash, paying comic book, movie, video game fans are usually male and do NOT want to be lectured to by SJWs forcing a "Girl Power" agenda. Nor do they care about the gender, race, creed of the main characters as long as the story is compelling and the movies/games are well made.
