In a given case, gender dimension might be irrelevant or of low importance, yes.But to think about is not such a ridiculous thing!

"Gender Dimensionality as Applied to the Vocalization of Task Coordination on Ocean-Going Vessels" - there's your paper's title.

Which is what we're arguing about. Not the historically constructed gender dimensions (I'm thinking you should put the Thesaurus down and walk away, because your word choices are actually obfuscating the thing that you've identified as the issue, but I digress), which I'm reading as "these songs used to be sung only by men". Yes, it's about gender, but it's about gender because that's the ONLY factor the OP focused on. It's not the only bit of ex-status quo that's changed. It's conveniently, the one change that gives men, in general, license to sing.

And PFR, I applaud your non-discriminatorical apathy.
