Yes, cooking shouldn't be a gender-based skill.
However, I find your point that looms over attractiveness and jealousy a little problematic. I don't think it is about the attractiveness scale because attractiveness is subjective. More so, the idea is majorly about being women dependent on their partners- and how it is problematic because if the relationship were to end, women will be left with nothing but a visible career gap. Also, I don't understand your point about appearance challenges? Do you mean to say that unconventional women aren't are part of this stay-at-home girlfriend fad? My friend, you have missed my entire point. It is never about appearance but about the levels of privilege one has over working and not working. With that being said, have a good day! :)
