Unfortunately, I agree with
@The_Cosmos these rulings are heavily supported by Quran and Hadith, they have to be to be taken seriously. Shockingly, even the sheikh from that other thread calling men whose wives attend Western universities to become "Doctors, Teachers," cuckolds was justified in his position per the Islamic perspective of free-mixing of men and women.
Even families are heavily segregated in places like Saudi Arabia, their homes have two living rooms wherein the sisters and mothers dwell in one and the brothers and father dwell in the other. When they eat, one large communal plate the boys eat from with their father, and the girls eat with their mother from another, etc. It's engrained in the society down to the family unit. They live almost completely separate lives. To think of the real world consequences, clashes, and barriers to a respectable education his sermon caused the women in the lives of those men who were influenced by it...in Australia, no less is amazing.
