I guess if that is what it is, then it is no more of a waste of time than watching movies all day. But can’t they find something productive to do?
If you had no chiyuv limud hatorah would you never learn. Didnt they teach in the yeshiva you went to that torah helps a person get close to hashem and understand his ways? and that learning makes you a better person(in a different way than putting on tefilin or shiluach haken does)?
Why cant that be an asperation a woman as well(my question is only in a case where the woman is interested in these things. you were were that there could be a case when a woman was learning not for feminism, but indicated that it would be a total waste of time )
