You are confusing Islam with militant extremism,. A little fact for you, since 2001, 3,114 American have been killed on American soil by terrorists. This includes all of those killed in the WTC. In the same period, 44,000 Americans have been killed by other Americans. The rest of the world should build a wall around us. Also, more than 1,000,000 Iraqi civilians were killed when we "liberated" them. Any wonder some in the Arab world do not like us?
