Well there is a great difference between 'learning', that your people start at madrisa at a childhood age...learning without questioning and study or analyze, that dependes on enquiries, doubts etc.
And if there is no difference, why you start panicking when we study or analyze Islam?
Re Dar-ul-harb...study posts of your co-followers and tell me who is right or more right!
when you study and analyze...put your doubts and then seek the answer with open and clear mind............................you eventually learn something.
