If you're wondering what I'm talking about for a while "feminine vocal fry use" was a whole thing: http://theguardian.com/commentisfree/2015/jul/24/vocal-fry-strong-female-voice …

The driver might have misophonia, and part of his coping may be to try to minimize environmental triggershttp://misophoniasupport.tumblr.com/triggers
Yes maybe and I considered this possibility at several points in the rest of the thread, yet conclude the note remains needlessly hostile
It was a bad note, for sure. As someone with misophonia though, I know if you have a vocal trigger, the gender of the person doesn't matter.

Of course. To be clear, I think the sign was very inappropriate. But I don't think it was directed at a specific gender.
I think it's impossible to ignore the possibility that it is about gender, especially given recent focus on fry in gendered contexts
Agreed. I was only offering another, less sinister possibility. Maybe you'll get the chance to talk to the driver about it.
Yep, didn't register at first for me either
