‘When women “switch” sides so they are the ones celebrating the Torah they are essentially declaring their desire to do that which God has said is not wanted.’
If God really didn’t want women to dance with a Torah scroll, He would have said so.
“Any communal change that doesn’t have this motivation, as noble and legitimate as the motivation may be, by definition is changing our Judaims from a more authentic version.”
Indeed the authentic version of Judaism is that women are not prohibited from dancing with a sefer Torah.
A more interesting question is why the things even MEN do on Simchat Torah are permitted — it was a change from the “more authentic version”, significant changes in normative practice (>5 aliyot on YT, leining at night, delaying the leining until after dancing, birkat kohanim at Shacharit and not at Musaf….), not ordained by any gedol or beit din, and something that spread from the bottom up in the diaspora. But Judaism survived that change. (And it will even survive Maharats!)
Gmar chatima tova!
