...teachers tought Arabic but also taught islamic philosophy and the nuances of the Quran and hadeeths, lessons were centred on interpretation and context of quran revelation and philosophy. For example our teachers would recite a verse talking about "killing the infidels" and would explain the context of these verses being in wars and self defence against malevolent judeo christian tribes at the times of the prophet and how in peaceful times, Muslims are obligated to respect and foster healthy relations with other faiths, backed by verses in the Quran and hadeeths.
For the Life of me i dont understand why such an understanding is lacking. It would seem that anyone who is at all sincerely interested could come to this. I guess that may be the problem - people arent sincerly interested in learning to discover what a text is trying to convey. Perhaps some people are just interested in obeing authority, "being right" and joining some group instead.
Now if people were TRULY educated on what it means to "Know-how-to-read-certain-text" some of the foolishness may be reduced. For, You cannot just pick up a novel and read it the same way you'd read poetry. OR read the Bible (Quran, Gita, Sutras etc..) the same way you'd read the news paper - yet this is what I see from several people i've encountered.
(HOW TO READ A BOOK: by Mortimer J. Adler is a great place to start, IMO)
