^^ lol if there's no room there isn't much u can do i guess innit? the only thing i can think of is i guess u might wanna go to the next nearest masjid which has space if you're keen on going.
at one of the masjid i pray in, the masjid gets so packed with bros that i think they endup hijacking the sis section lol, so the sisters tend to not b able 2 attend the jumuah.. but its nothing to do with the bros trying to deprive sis's of attending.. it's jst the way it is.. no room.
but i'm pretty serious... the female sahabiyah's use to put the Khalifah's in their place even during khutbah, no one called that rude or obscene or anything so long as she had teh evidence with her.. so don't let these imam's dodge u by saying 'who r u to argue with me' etc...
