Winning because you were given a huge handicap isn't exactly winning, I literally cannot imagine in what world you see this kind of thing as some kind of net win for these kinds of movies.
Like, fuck i'd be pissed if I was an Actor or Director and found out the only reason I won was because my movie met an arbitrary percentage based diversity quota. it'd be sending a message that my movie wasn't good enough to win without a handicap, my award would feel meaningless and insulting to the hard work put in it. Its not just pandering, its empty pandering, this will have no positive effect on these movies and instead just draw negative attention and stigma around them as "Not good enough to stand on their own".
I guess I'm just not woke enough to consider LGBT/Minorities driven movies to so much inferior to Whites that they couldn't win Best Picture over something like fucking Paul Blart Mall Cop.
Edit: And since I know this is the level of stupid we're probably driving too - Woman led, Black led, Homosexual led, I don't legitimately give a fuck whos in your movie, whos the lead, whos the ensemble, nothing. A good movie is a good movie and a shit one is a shit one. Now if you'll excuse me, I'm going to go watch Beverly Hills Cop again to renew my woke cred. Fuck man I love me some Eddie Murphy.
Edit2: Side note: If your argument is that limiting best picture to these criteria will lead more directors/etc to make movies that fit that criteria in order to somehow artificially inflate the diversity representation in movies? Until China gives a shit I don't see this doing a darn thing. But I'd absolutely understand (as naive as it is) if you were arguing this. So, if thats your stance, feel free to just move on with your life because I have no argument for you.
