I would not consider her stupid for what she (or others fighting for their rights of education) did. Besides, a lot here complain about "how so barbaric" and "they're living in the past" these countries are, and calling the people who wants to just have an education stupid is something I can't understand why. I guess you'd rather these girls marry at the age of as young as 10 (or even younger)? By the way, the guy who won along with Malala also fights for children's rights in India.
I wonder how many of the people here in the forum would be doing what they're doing? A lot complain but not doing any action to change something.
