I guess I'm the only one that can see where Zainab is coming from, then.
These views have been implemented on her since she was a child, her parents had the same treatment and their parents before that, and so on. To say Zainab is a strong woman would be correct in some ways, but she is not strong enough to fight for what her son believes in, when the religion she believes in and her whole community see it as wrong.
It kind of reminds me of the programme "Keeping Up With Appearances", Zainab is trying so hard to be seen as keeping this perfect Muslim family and such, but unfortunately it's falling apart at the seems.
