From a certain perspective, it's 'demeaning and patronizing' to elevate individuals beyond their true valour, for whatever purpose. People are more than their 'race or gender' and most musicians define themselves as artists or musicians first, not by their gender, i.e. not 'female musician'. So to be treated by a different standard may offend their sensibilities as artists or professionals, i..e the part of them that is not oriented towards the specific aspect of intersectionality.
The Army is not the arts ... but for whatever reason at least in that organization the women generally really, really don't want to be treated differently. It's nice to be the 'first so and so to do such and such' but that's definitely not the point. They're not 'Lady Rangers', they are 'Rangers', full stop, and generally don't want a sliver of space in between what they are, and what the Men are.
Having not heard the music of 'Women With Transistors', I could be wrong ... but I'll suggest they're not on par with 'Beethoven'. So the issue then becomes the degree to which these ladies were overlooked, possibly due to sexism, and the nuances in that. That's the story. And there's a lot to unpack there obviously.
I think the controversy arises because some people question the legitimacy of comparisons with 'historical greatness' and then others interpret that to be a form of delegitimisation of the challenges the women faced, or that they were overlooked. Which could be true in some form of rhetoric, but I think is not true on it's face, or rather, it's a least reasonable to question whether or not the people in question here are 'Beethovens'.
And I'll say again - I haven't seen it, so I can't really be sure of this specific case, rather, I'm explaining how confusion can arise in these kinds of cases.
But it looks like an exciting watch for sure.
