Its true muslims rulers have followed a very cowardise approach through out their small history because they were scared and insecure of other religions preaching peace and harmony. thats y they destroyed such great centres of learning such as nalanda because of their inner insecurity and inferiority complex. Even if u look today all muslim terrorists are COWARDS who hide and kill people, if they are brave enough they shud come in the battlefield and wage a war,but sadly that wil only happen if they hav any mettle in them and since they dont they only hide behind the bushes and fire that all they know
