Well, Except When Our Imams Are Supporting Terror
A headline on HuffPo, from a piece by Shahien Nasripour:

Boston's Largest Mosque: 'We're Bostonians -- We Mourn With The City'

And then there's this:

"Imam Abdullah Faaruuq ... calls convicted al-Qaeda member who attempted to fire on U.S. soldiers 'brave,' condemns soldiers as 'kafirs.'"

From Jihadwatch:

...well-known religious leaders with connections to Massachusetts political and civic leadership were involved in this campaign. Among them was Imam Abdullah Faaruuq, then the Muslim Chaplain at Northeastern University and a frequent preacher at the largest mosque in the Northeast, the Islamic Society of Boston Cultural Center.

More about the Islamic Society of Boston Cultural Center from Militant Islam Monitor:

The ISB was founded by Abdulrahman Alamoudi. He is currently serving 23 years in prison on terrorism charges.

An original trustee of the ISB, Yusuf Qaradawi, is the spiritual leader of the Muslim Brotherhood. The Muslim Brotherhood is a global Islamist organization and a key source of worldwide Islamic extremism.

Current ISB President Osama Kandil was a director of Taibeh International- a Muslim Charity designated as a terrorist entity by the US Government in 2004.

Jamal Badawi, a recently appointed Trustee of the ISBCC, was named an unindicted co-conspirator in the trial of a Muslim charity, The Holy Land Foundation. [1] The Holy Land Foundation trial recently resulted in federal convictions for the illegal distribution of money to Hamas; a designated terrorist organization.

The ISBCC is now controlled by the radical Muslim American Society (MAS). U.S. federal prosecutors have identified the MAS as 'the overt arm of the Muslim Brotherhood in America".[2]

The majority of the funding for the center's construction came from Saudi Arabia and the Persian Gulf States. Saudi Arabia practices Wahhbisim, an extreme brand of Islam that promotes a return to Islamic orthodoxy as taught by the 7th century prophet Mohammed.

The ISB has attempted to hide the identity of its true leadership by rotating trustees and board members. They falsely state that a new local board assumed control of the center from the prior mostly overseas based trustees. When the ISB became too controversial, the leadership re-branded the ISB into the (MAS)Muslim American Society's Boston Branch.

In addition to these hard facts, a recent speaker invited to give a talk at the ISB's Cambridge Center, is also very troubling. The speaker, Sheikh Yasir Qadhi had previously denied the Holocaust, claimed that Jews want to destroy Muslims, and called all non-Muslims a "spiritually filthy substance" whose lives and property hold no value. This audio of some of his talks can be heard on www.hatefreeamerica.org.

A sura in the Quran (2:190) commanding jihad is here:

By abandoning Jihad (may Allah protect us from that) Islam is destroyed and the Muslims fall into an inferior position; their honour is lost, their lands are stolen, their rule and authority vanish. Jihad is an obligatory duty in Islam on every Muslim, and he who tries to escape from this duty, or does not in his innermost heart wish to fulfil this duty, dies with one of the qualities of a hypocrite.
