It's simply an unavoidable fact that across history almost all composers have been male. This is changing, but still as far as I know women remain significantly in the minority among contemporary composers.
Any discussion about classical music generally will inevitable focus almost exclusively on men, and this will perpetuate to some small degree the suggestion that composition is male territory.
So I'm totally in favour of making an effort to highlight the contributions of women to composition - and especially the contributions of today's women. If this is looked down on as "affirmative action", so be it. Granted, I don't see the merit in praising a mediocre composer ahead of other, better composers just because she's a woman; but equally I don't see the merit in snitty counterclaims of "you only praised her because she's a woman" in the absence of any evidence of same. [For the sake of the argument I'm ignoring my own preference of avoiding terms like "mediocre" and "better"!]
I don't think any of us could tell by blind listening whether a piece was written by a woman or man, and I think there's value in someone looking over their own collection of (contemporary) music, seeing what percentage of it is by women, and having a think about whether that figure seems reasonable.
For instance, looking at one of my playlists, of my favourite music of the 21st-century, I see 19 male composers and 2 female. This strikes me as a bit low on the female side, in the following sense: let's say one of my kids looks at that list and asks "Are composers nearly always men?", to which I respond "Well, a lot of them are; as far as I know about 15% of newly performed music is by women", to which they respond, "I've done percentages at school - 2 out of 21 isn't even 10%. Why don't you have 15%?", to which I reply, "I don't know. That's just how it worked out", to which they reply, "That's not much of an answer, is it? Perhaps because you're not making enough affirmative effort, you're merely passively perpetuating a wholly unjustifiable male dominance", to which all I can say is "Go to your room!"
