I highly doubt Mr. Leavings  has ever read the Qur'an  or any book on Islam not put out by the "Muslims are here to kill us" cottage industry.  Muslims are a  religious group not a homogenous ethnic unit.  The single largest group of Muslims in America are African-Americans at 35%,  where would you send them off to?   As if this  needed saying  muslims have sworn allegiance to this country (and yes, even on the  Qur'an)  beginning with the Civil War.  The first person of a culturally Muslim background arrived in Eugene just over 100 years ago,  selling tamales from a horse drawn cart down Willamette Street  he later operated a wholesale poultry and egg business  for 50 years on the present site of the Hilton. 
 The causes  of terrorism are  complex; mostly relating to poverty and oppression by authoritarian governments (often backed by the US) repression breeds  extremism in certain kinds of people. Its not like misguided people have never acted in the name of Christianity.
