Torahlishma-
I don’t think the Shulchan Aruch is that clear that women shouldn’t learn Gemara. While the S”A does say that anyone who teaches their daughter Torah (which we assume to mean Gemara) is as if they were taught tiflus, the S”A also says they receive sechar for learning Torah. If you look inside, it’s very clear that the same Torah that women receive sechar for learning is the same learning that is considered tiflus if taught to her. Obviously there are many ways of reconciling this, but my point is, is that it’s not clear that the S”A says they can’t learn. Why would they receive sechar for doing something they shouldn’t be?
