The article is about terrorism, when you compare terrorist acts done by Muslims to all the other acts of terror in the US, the percentage is very small.
When you want to compare sugar in a gas tank to 911 your trying to frame the argument in a very dishonest way, or you have some kind of mental issues. Most people can see through that in a heartbeat, I'm going to assume you may not be aware of that. You often make these kind of crazy leaps
Here is a list of terrorist acts in the US, in case all you can think of is 911, a pipe bomb and some sugar in a diesel tank
