I believe that the decision they made was perfectly acceptable and valid. What they don't focus on in this article is the fact that the girls have continued their studies while travelling around the world, although I feel like the lessons they are learning as they travel are more important for life, culturally than anything they could learn at school. This opportunity is rare and should be taken with open arms. The parents had the legal right to remove their children from school and take them around the world- they're not completely separating the girls from their studies and have worked with their previous primary school to create a smaller curriculum that the girls can learn as they travel. So they shouldn't be punished or perceived in a bad way for following their decision to travel.
