The roots of radical Islam not found in poverty or discrimination

Washington Examiner:

The rise of homegrown jihadists such as Dzhokhar Tsarnaev, condemned to death for his role in the Boston Marathon bombing, has caught counter-terrorism analysts off guard.

"What's puzzling is that Tsarnaev was hardly an observant Muslim" said Peter Bergen, CNN's national security analyst. In fact, Tsarnaev's tweets had almost nothing to say about the practice of Islam and were typical for a 19-year-old American student interested in "sex, girls, marijuana and alcohol."

So how did Tsarnaev become a jihadist? Because he was radicalized in the United States, the usual factors used to explain jihadist behavior — poverty, illiteracy, discrimination — do not seem to apply. The answer lies instead in the method developed by the Muslim Brotherhood to advance Islam in the West.

The Muslim Brotherhood traces its roots back to Sayyid Jamal ad-Din al-Afghani, a late-19th century Islamic scholar. Al-Afghani originated three key ideas. The first is pan-Islamism, which encourages Muslims to set aside their disputes and unite. The second encourages Muslims to return to the original ideas of Islam as taught in the authentic Islamic sources. The third admonishes Muslims to take whatever actions necessary, including eliminating apostate leaders, to overcome obstacles that might impede the movement.

Tsarnaev's radicalization was a product of Al-Afghani's efforts to revive Islam by teaching from the authentic Islamic sources. Radicalization is nothing more than the belief that the traditional interpretation of the Islamic sources is the true interpretation. The traditional interpretation flows from the literal language of the sources, so just teaching the sources is sufficient to ensure that young Muslims come to accept the traditional interpretation.

The root of the problem is in the religious bigotry within Islam itself.  The radical Islamist are all religious bigots who are intolerant of anyone including other Muslims who do not follow their weird beliefs.
