How about women working? Is that also a shas hadchak? If you say yes because these days a family needs two incomes, then tell me how it is that there are families with 10+ children in which there is only one income, and it’s coming from the Ima.
The bottom line is “there’s no mesorah for that” is a silly and weak argument. No one seems prepared to argue that this is halachically assur, but I still haven’t seen a real case for why it’s not otherwise appropriate other than that it makes some people uncomfortable. And I can tell you that women not participating on Simchas Torah makes me uncomfortable. I know I’m not the only one, either. So whose comfort is going to take precedence?
