ThePurpleOne: Apologies for the misunderstanding. I didn’t mean to imply that. Certainly, some women are outgoing and funloving, and they can have lots of friends, have Purim parties, enter the caring professions or other jobs that involve a lot of social interaction, get involved in organizations, chesed, etc.
My point was that only men have the special need to have certain public roles in shul unique to them, for them to feel fulfilled and thus keep them away from sin.
Some women may also feel drawn to public roles, and they can do that too. But women in general don’t feel that need — so their own personal relationship with Hashem (through personal prayer and the many mitzvos that apply to women), and their bonds with their spouse and children and other family and close friends, is enough for them to feel happy, stay away from sin, and advance in their avodas Hashem.
Women are more grounded in their social relationships and are naturally more nurturing and compassionate, while men often have a tendency toward anger and harshness and arrogance and impulsivity, which needs to be restrained through extra mitzvos (such as more time spent on Torah study and at shul). Everyone has their own needs and challenges, and the halachic differences between men and women reflect that.
Anyway, these are just my own ideas about why things are the way they are!
