Vocal fry is not per se an "affectation", need not be the result of "throat constriction" due to anxiety, need not lead to damage to the voice and is not confined to a gravelly sound tailing off an utterance if someone is bored or wants to appear bored.
Some of the ways it is being described are as if it is the vocal equivalent of nonchalantly and superciliously blowing smoke in someone's face.
What you seem to be describing Huntlybyelection is a "vocal tic" or non-verbal vocal gesture that happens to include some vocal fry. Not vocal fry per se as a voice quality. It seems as if people might be talking about different things - unless it is just me who has got the wrong end of the stick!
The article linked by the OP suggested that it was vocal fry in general that was being discussed. It might have become "fashionable" but do PP find it irritating because of how it sounds or because of who has "popularised" it? Kim Kardashian was mentioned - I have no idea what she sounds like.
If woman are deliberately adopting a lower-register speaking voice, forcing a "dropped larynx" with increased muscle tension then vocal fry can be a by-product rather than the aim.
The same applies to men. Typical jobs that result in men damaging their voices because they try to adopt a deeper, more authoritative voice: barristers, priests, rabbis.
It is much less common for a woman to damage her voice due to adopting a lower than natural register - natural for her, not for women in general.
Women's voices are far more often "pathologised" than men's and women are far more likely than men to be pathologised for the sound of their voices. They present for therapy when there is absolutely nothing wrong with their voices but someone has made fun of them or slurred them, they are shamed and humiliated and think something is wrong with them.
Women's voices are naturally much more "musical" than men's, more expressive with a wider pitch range and greater use of intonation to express meaning. A woman's voice does not have to be deeper than usual for her to be singled out and "diagnosed" by others as having something "wrong" with her, medically, morally or ideologically.
It can just deviate by being less varied in intonation and stuck in the mid-range (is she boring?? is she bored?? is she depressed?? is she autistic??) or higher range (is she hysterical?? is she over excited??) or the low range (is she threatening?? is she angry?? is she sullen??).
Most people are very good at picking up cues from the sound of someone's voice and that can be a great aid to empathy. Or it can be turned against someone.
There have been some brilliant women speakers at events over the past couple of years, at meetings discussing women's rights and the GRA. Many of them have what might be characterised as "girly" voices. Some might decide that that indicates they must be air-heads but I would hope that most women here would not have such stereotypical ideas about how a woman "should" sound.
I have to say that I have been gobsmacked by some of the negative, judgemental comments in this thread on a Feminist board.
Most women's voices sound the way that they do because of their individual anatomy and environment, not due to affectation. A "raspy" voice might be "natural" because her mother spoke like that, or she works in a dusty environment or a call centre. To suggest that it is all "affectation" and "irritating" is like having a dig at women for the shape and size of their breasts or their teeth.
For my own part, my voice is naturally deep for a woman. I went through the humiliation of not being allowed to sing at school, sent to sit on the sidelines with the couple of boys whose voices were breaking early.
I always loved singing but would only dare sing if I was alone. I was in my fifties before a friend who was a trained singer overheard me, said that he thought my voice had a good "tone" and potential and encouraged me. I now perform in public regularly and have been recorded. (it's never too late to do something that you love!)
I also prefer female voices on Sat Nav. As mentioned above, the higher register cuts though engine noise better. I also don't like a man as a back seat driver!
