According to the Investigative Project On Terrorism, The Islamic Society of North America , ISNA "is one of America’s most prominent and active Muslim organizations.

While it enjoys a generally positive public image from its religious endeavors and huge annual conference, ISNA’s extremist origins and continuing ideological support for radicalism make it an inappropriate partner for government outreach.

As the information detailed in this report will show, ISNA’s ideology has been rooted in radicalism since its foundation.

Among the findings:

ISNA remains an unindicted co-conspirator in the Hamas-support prosecution of
the Holy Land Foundation for Relief and Development (HLF), despite its appeals
to the court to remove that status.

ISNA was created by members of the Muslim Brotherhood – a radical Egyptian
movement that seeks to spread Shariah law globally – in the U.S. Many of those
founders remain in leadership positions with ISNA.

It invites controversial speakers to its nationwide conferences, including some of
the world famous Islamists and advocates of Jihad.

Speakers at ISNA conferences make radical statements, often in contradiction of
ISNA’s cultivated public image.

Rick Warren seems to take pride in his participation in the ISNA national conference.

Under the Islamic theocratic rule of sharia, a non muslim living in a jihad conquered land is considered a "dhimmi" , that is, subject to sharia law.

Warren is either a dhimmi and doesn't know it or useful idiot. Or both.
