You focus on ONE thing that's not historically accurate. I wonder why it's gender, and not the purpose of shanties, the location where they're sung, and the reason they're sung. You go don't the list of things changed so the shanties can be sung, and you come up with gender.

I'm think it's the single thing the "He-Man Women Haters Club" can focus on that will let THEM keep singing.

We see you. (And we know whose problem it is.)
