Toi-
Not sure if you’re serious or not… but if you are, I don’t think that’s what the Shulchan Aruch meant. The S”A clearly says that women receive reward for learning. I don’t think Adam received reward from eating the Eitz HaDaas.
Rationalfrummie-
It doesn’t sound like it’s a bedieved. S”A opens up with they receive sechar and only then says that it shouldn’t be taught. If sechar was only if they learned bedieved, I would have expected the S”A to begin with that it shouldn’t be taught to them and only then mention but if they do they still receive reward because it’s Torah.
Beniguman- That’s how I understand it. Since they aren’t obligated to do it and some aren’t able to it properly, it shouldn’t be imposed on them. However, a woman who is capable and wants to do it (for lishmah reasons, not feminist ones) can and should learn (as long as it’s not coming at the expense of areas of Torah that she is chayav to learn).
