Ummm... I know a bit about Judaism
. Then again, they are not second class citizens either.
One could probably have a very long argument about second, third or maybe some fractional class that women occupy in Judiasm.
As an non numeric illustration consider this: every
Jewish male is required to give thanks to god every morning
and in particular "Baruch atah…she lo asani isha." that is "Thank you god ... for not making me a woman".
