From The National Catholic Register:
Fr. Rutler on Islam:
The World Trade Center [on 9-11] was not destroyed by Presbyterians. Catholics are naïve if they try to ignore that the attackers were Muslim. As I said in one of my articles (http://www.crisismagazine.com/2014/mad-intelligence), society is in a similar place today as it was in regards to Hitler in the 1930s. People were accommodating themselves to National Socialism or Hitlerism because they thought it would bring down Marxism. The Nazis, in fact, presented themselves as the anti-Bolsheviks. But, they didn’t appreciate the disease they were unleashing on the world.
People who describe themselves as liberals today are often protective and defensive about Islam, despite the fact that it is so intrinsically opposed to what these progressives claim to represent. The only explanation I can come up with is that these Western socialists or progressives are hostile to Judeo-Christian civilization and see Muslims as an effective force against it. The enemy of my enemy is my friend.
This is coupled with the fact that the secular media so often downplays or ignores the atrocities committed by Islamists. Just recently, for example, four Christian children were lined up by ISIS in Iraq and told to deny Christ and convert to Islam. When they refused, they were decapitated. I don’t recall seeing that in the New York Times.
