I join with many others, who state they learned all they need about islam on 9-11-2001.
Events which followed merely reinforced those impressions, negative.
I had an earlier experience when Iranians held Americans as hostages. That was when I learned about Taqiyya--lying to further islam and/or protect one's self.
Judaism and Christianity have gone through reformations, and become "modern" and non-violent.
Islam needs to become modern as well, rejecting violence, discrimination against other religions, separation of church and state, etc.
