Not one person here has actually said how they define "masculine" and how it pertains to judging a Tarot deck. They just say they get a "masculine feel" from it, or from parts of it like the "tone of the artwork" and everyone just seems to agree without giving reasons. What does that mean?
I did actually query the OP regarding what they regard as masculine, but they didn't respond (as far as I can see, may have missed it).
We're basically going on convention, of course. Leather and brass tradition, or racing-cars and girls, pirates and vikings, whatever is the opposite of pink and soft and sweet and cute. (insert Judith Butler quote of your choosing).
