I think you got wrong.......the afghan taliban where against mixed education of boys and girls in the same school and not against girls education.
I think you got it wrong, the taliban were totally against the girl's education, mix or not mix didnt matter to them. There was no any SINGLE girls' school in their area of control, women werent allowed to go to work, women werent allowed to go to universtiy, even little girls at primary school werent allowed to go to school. It is worth to note that even the boys school/uni had the lowest of low quality. Girls education was kinda illegal activity which went underground and families used to hire teachers secretly to teach their daughters in small numbers at their homes, probably selling of hashesh and heroine were less of a crime than girls' ecuation. Here is something for you to read from BBC: Until recently, girls in Afghanistan were denied the right to go to school.
Under the Taleban rule, from 1996 to 2001, female education was banned. Women and girls were excluded from all aspects of Afghan educational life, from primary school to university.
The government closed all of the girls' schools in the country and prevented female teachers from working.
Many parents feared that their daughters would grow up illiterate. Some girls were secretly educated in their homes by parents and teachers; others attended underground schools.
The majority of the leadership of the taliban where well educated and where not against people getting an education.
May I ask which one of them had which education and where they were educated?
Note: my sisters and cousins used to go to these underground schools as that was the only and only hope and opportunity for them to get some education.
