Um if a woman has time to waste (which is not very likely to begin with if she has kids), i think masjid wud be the LAST place she'd go to for time-pass.
Also, going to socialize and wanting to get to know more people and be part of a community....thats not "timepassing" or wasting time either. or wud ppl rather that women not know anyone aside from their inlaws/immediate families?
Eid is a moment to gather and to be happy while meeting each other, BUT all those in laws and out laws must obey the respect and dignity of mosque and the khutba being offered. It is what almost always being told in the mosque where I offer my prayers, whenever people (men, kids and women) starts talking during any Islamic teachings.
I went to taraveeh and I was more than upset to see lack of respect on women's side. The Imam had BEGUN the rakats and women were standing around chatting, then getting up to read along when they felt like it. I don't understand why they can't stay at home if they have no interest in reading and only show up to gossip.
Maybe because there is no one to call out their behavior.
Our Imam - takes away the partition when the friday and EID khutba is going on and seriously will "PUT YOU IN YOUR PLACE" if you are not there to worship at the time for prayer.
