I am against this too. I am not a huge believer but respect those who have views. But like Graham has said it is a slow drip drip drip by the few to the masses. I can remember when I was at school we had a real 'old school' master who could make the bible stories sound exciting and fun, but after he retired we had a 'new age' type of teacher who was Jewish. From that day on I turned off. He forced the Torah down our throats and even made us have to remember and recite different passages of the text and I remember him getting really angry at a lad who refused to do it. He even took us to 'his' synagogue 40 miles away in a bus, just so we could see him praying. From that day on it turned me against faith, but I still remember the stories from our first master, and therefore the moralities of the text. I really do not see that teaching more Islam history is the best for those who don't want to know about it.
