Dr. Hamid, a onetime member of Jemaah Islamiya, an Islamist terrorist group, is a medical doctor and Muslim reformer living in the West.

While there are many ideological "rootlets" of Islamism, the main tap root has a name--Salafism, or Salafi Islam, a violent, ultra-conservative version of the religion.

It is vital to grasp that traditional and even mainstream Islamic teaching accepts and promotes violence.

Worst of all, perhaps, is the anti-Americanism among many Westerners. It is a resentment so strong, so deep-seated, so rooted in personal identity, that it has led many, consciously or unconsciously, to morally support America's enemies.

Well-meaning interfaith dialogues with Muslims have largely been fruitless. Participants must demand--but so far haven't--that Muslim organizations and scholars specifically and unambiguously denounce violent Salafi components in their mosques and in the media. Muslims who do not vocally oppose brutal Shariah decrees should not be considered "moderates."

When Westerners make politically-correct excuses for Islamism, it actually endangers the lives of reformers and in many cases has the effect of suppressing their voices.
