We all need to come to grips with the fact that the left has completely unsubscribed to the very concept of Islamic terrorism.
They have done this so thoroughly that no atrocity, no matter how horrific or brutal, and no matter the overwhelming evidence for Islamic religious motivation, they will attempt to find an alternative explanation.
In essence, they have bought what the Islamo-Nazis are selling, and are allowing themselves to be used as enablers of the global jihad.
“We all” already came to grips with “useful idiots” among us here on FR. Most of us, anyway!
