You know what destroys Calliopes gendered classes theory? Bards have no gendered connotations, so why would they be a male only class? You could argue it's due to the cod piece, but it seems god tier suits can be modified and vary according to Meenah, Sollux and Meulin.

Good grief, who WOULDN’T want to wear a magnificent Codpiece like the Bard’s, of course it’s unisex.

In all seriousness though, it was either a mistake by Hussie that he corrected, or just intended to be another theory by Calliope, she’s explicitly a Theorist after all. Regardless, considering as… Distasteful as the Cod Piece boner may be, having it be a male-only Class BECAUSE of that would be a tad transphobic. If anything a better reason would be the Prince-Bard duality- With ‘Prince’ being a male-coded name, just as ‘Witch’ is female-coded. But yeah, Classes are not Gendered.

What sells me on the idea that it was intended to be a debunkable theory from the beginning is how arbitrarily she sticks to the idea of Rogues and Thieves being a female-predominant Class. Like. There’s no reason why that’d be, other than the fact there’s 5 characters with the Thief and Rogue Classes, and only 1 of them is a guy. It’s a very biased point of view taken from an extremely reduced sample size.
