Avira > Aaq, a school that teaches gemara to girls as a part of the class that she must attend is definitely coercion
I agree that this is different from a unique lady who is interested in learning, but I am saying that, as far as I know, most people do not advocate for a universal obligation. Most MO will not call you to teach your daughters Gemorah. Furthermore, as far as a family is free to choose a school with or without Gemorah, and, presumably, the kid has some input in the process, it is not fully “obligatory”
On the other side, my daughters jump away when something might be a “mishna” or a “Gemora”. Maybe they were told that it is bad for a shiduch, not sure. At the same time, they are familiar with most of the material that I overhear from my Daf Yomi, except the pilpul and inappropriate topics. They just were not told at school that these are Gemoras.
