The problem with most people is... that if only 25% of any alternative explanation for many of these terror events is reality then it would be time for everyone to get active in some way. People don't want to have to do anything short of voting and sending an occasional letter to your local politician. Instead, they want to watch them some wrestling and drink beer and complain about how them hajjis are taking over while daydreaming about being Jack Bauer or Chris Kyle and fighting those hajjis. They don't understand things because 1) the world has become so complex that few people have energy to look into real explanations as to why certain things are happening 2) they just don't want to understand and instead choose to burry their head in the sand.
I'm starting to think it's all about advertising. Like the new Iron Man movie. Create a situation for your new product. It's the new marketing.
