I’m basing it mainly on the dismissal of a halachik concept because she had a kasha on it; that’s not something one would do if they had even a rudimentary training in basic 7th grade gemara.
I’ve yet to see a “shtikel torah” by a female author that isn’t divrei havai – i actually have to mention that i realize that that’s what you’re referring to when you said shtus…
Creating a situation where torah will be made into divrei havai is assur because of kovod hatorah; men might do the same, but they’re obligated, so they’re onsim if they do so
