They are driven by their blind hatred for the US and all non-Muslims.

Muslims who are outraged by an amateur film produced by an Egyptian Christian do not seem to be equally offended when many crimes are committed in the name of Islam.

There are only three reasons why Muslims could be speaking out against the terrorists. First, fear of retaliation. Second, indifference to what is happening. Third, identification with the goals of the terrorists.

For these radical Muslims who are rioting in Cairo, Tunis, Khartoum and Sydney, the film was just an excuse to vent their anger and hatred toward the US, Israel and the entire Western world and civilization.

What has been happening in most of the Arab and Islamic countries in the past few days is more about hating the US and Israel than defending Islam and Prophet Mohamed.

The violent protests should serve as a reminder that radical Islam, which has been hugely boosted by the "Arab Spring," remains a strategic threat to all those who believe in freedom, democracy and equality.

The anti-US protests were just another episode in the war that radical Islam has declared on the West. The US is hated mostly because of its support for Arab dictatorships as well as its support for Israel. The extremists also hate the US because they see it as an obstacle to their efforts to conquer the world and establish an Islamic caliphate.

Instead of staging demonstrations against Muslim extremists who kill innocent civilians every day, Muslims are directing all their anger against a poorly produced trashy film instead of protesting against terrorists who have hijacked Islam, committing some of the most heinous crimes.

Shouldn't Muslims be more worried about all the jihadi groups that have sprung up in the Arab and Islamic countries in recent years and whose members are imposing a reign of terror and intimidation on moderate and peaceful Muslims?

When was the last time Muslims took to the streets to protest against suicide bombings that have killed thousands of innocent civilians in Iraq, Pakistan and Afghanistan?

When did Muslims ever stage demonstrations to protest against Al-Qaeda's 9/11 attacks, in which nearly 3,000 civilians were killed in the name of Islam? Perhaps because many Muslims do not believe that Muslims carried out 9/11, or because they believe it is alright to kill infidels.

Why aren't Muslims demonstrating in the streets of Cairo and Benghazi over the daily massacres that are being perpetrated in Syria by Muslim jihadis and the regime?

What happened to those Western-educated liberal Muslims who reportedly triggered the "Arab Spring" protests in Tunisia, Libya and Egypt? How come they haven't taken to the streets to demand an end to the violence and crimes that are being perpetrated every day in the name of Islam?

What are Muslims doing to protect the rights of women in Saudi Arabia, Sudan, Afghanistan, Iran, Somalia and the Gaza Strip?

What have Muslims done to stop the phenomenon of young Syrian girls who are being sold for "pleasure marriages" to wealthy men from the Gulf?

Where are the street protests against human rights and media violations in the Arab and Islamic countries? Aren't most of these violations and abuses being committed in the name of Islam?

Most of the Muslims who have been protesting the defaming of Islam and Prophet Mohamed in the Arab and Islamic countries have most likely not even seen the film; they are driven by their blind hatred for the US and all non-Muslims.
