She didn't say criticism from a particular group is dismissable.
She just dismissed criticism from an entire group by definition. As in:
X: I have an opinion on A.
Y: I have no interest in the opinion of X on A.
What is that if not dismissal?
And, yeah, this argument bugs me. It's always bugged me well before Brie Larson opened her mouth. I've seen this idea tossed around in numerous forms, though usually it's along the lines of "it was made for the fans" or "if you don't like it, why watch it?" Usually, it's a way of trying to dismiss any criticism without having to actually engage in that criticism. The latter arguably bothers me any more, because if you make something that's crap, and defend it with "it's for the fans," then by insinuation, your fans are happy lapping up crap.
More like, there's a particular insight that different people bring when critiquing. A cis critic and a trans critic will likely have different takes on Rocky Picture Horror Show. A straight critic and a gay critic may have different takes on But I'm a Cheerleader.
Um, yes? I'm not disputing that.
The point isn't to knock down white male critics but to uplift women, people of color, and lgbtq+ critics so that the conversation isn't dominated by a single group that potentially doesn't understand or appreciate what it does.
I know that's not the point per se - Larson made the point in a separate statement when she gave statistics on the demographics of film critics. However, again, it's effectively falling into the same fallacy:
X: I don't like A.
Y: It wasn't made for X. I want to know what Z thinks about A.
If we're really entertaining the idea that critique of art becomes more or less valid in sync with the identity/lack of it of the person reviewing it, then ultimately, the act of critique is worthless.
Also, it's telling that A Wrinkle in Time is the film being used as an example, said film being a box office bomb, and panned by critics and fans alike. Maybe the film just wasn't that good? Like, the whole "critics are out of touch" argument is conspicuously nowhere to be seen when critics and fans align. Apparently "the critics are out of touch, except when they agree with me" is the true message being imparted.
