OP you say we can't criticise others beliefs, this is not a belief it is a behaviour.
and YES, oh my GOD yes we can, and should criticise it.
I LIVED in that god forsaken place for 3 years, the abuse of people in general I saw was sickening. Children are broadly tolerated until they can run errands for their parents. Boys are raised never hearing the word NO, they are taught to control and abuse their sisters and eventually their own mothers by men that sit on their arses and expect the world and his lunch to be brought to them at the snap of a finger.
When you know better, you do better. We in the UK stopped beating our school children in the 80s, 30 years later, in Egypt it still goes on.
IME, they are both ignorant AND arrogant - a truly heinous combination, they won't have any other way suggested to them, and will condemn all those who don't follow their way.
The trouble I had trying to raise my DS there was mind-boggling. They insisted on trying to give him food, when I said he's not weaned. They tried to insist he ate salty or sugary foods when he was beginning to wean. I couldn't leave him alone with anyone, they literally would see it as a challenge to disobey my 'rules'. I was openly criticised because I put DS down for naps at regular times, and even more so for him having a bedtime. They don't.
The method for feeding small children in Egypt is to wind them up into a frenzy, and then the mother, or the maid, literally chases them around a room with a spoon and a bowl, shoving the food in the mouth when the child is distracted. You have to see it to believe it. I was 
the first time I saw it.
