The shameful part is always that the "millions of muslims who oppose" are almost always dead silent when they are needed the most.
True but reason seldom acts with the same speed as blind emotion. Look at the way Egypt played out.
Emotion stirred millions to demand that Hosni Mubarak be removed from office with the emotion being reinforced from abroad (Obama in the jumbotron in Tahrir Square) With that emotion still being propped up from abroad, they foolishly elected Morsi. After the election of Morsi that outside influence began to fade and the voices of reason within Egypt began to grow and overwhelmed the muslim brotherhood and before they knew it, Al Sisi was in power.
In a sense its similar to the warning Sam Houston issued against the civil war in the USA. He said southerners are fiery and impulsive while calling northerners calculating and determined.
