There are times in history when God, in His providence, allows people to see in full view the pivoting of history. Patriots assembling in Philadelphia experienced it on July 4, 1776. Navy sailors looking to the westward skies saw it on December 7, 1941. Families listening to their radios heard it on November 22, 1963.
The "Innocence of Muslims" trailer that has sparked deadly protests overseas is crass, intentionally offensive, and grossly inappropriate. That much is clear. As crude as the video may be, however, Google did the right thing in not removing it from YouTube because its content is not, in itself, what the law would call an "incitement to violence."
