Christians should be in the streets over this.

You can bet your Muslim friends would be.

On HBO's sitcom Curb Your Enthusiasm Sunday, comedian Larry David's character accidentally urinates on a painting of Jesus in someone's home -- and two women subsequently believe the painting is crying and they fall to the bathroom floor in prayer.

Hilarious, no?

No.

As world-class insults go, this one is a two-fer: Not only is it beyond outrageous that HBO would think it's funny to urinate on an image of Jesus -- humanity's revered Lord and Savior in the Christian world -- but to then cynically mock an entire religious faith's belief in miracles is an insult overlaying an insult.

Question: Would these "courageous" envelope-pushing comedy writers even dream of urinating on an image of Muhammad and mocking the Muslim faith?

We seriously doubt that, considering the riots and death threats caused by Muhammad cartoons in a Danish newspaper -- and the deadly riots that followed an errant 2005 Newsweek report that a Quran had been put in a toilet by U.S. guards.

Christians in America are much more tolerant -- and, apparently as a result, much more target-rich for ridicule and derision. How horribly sad, this state of affairs.

Religious tolerance is preached across the globe these days -- and, in fact, led by the Obama administration, the United Nations Human Rights Council recently decried religious intolerance and insults.

Funny how Christians always seem to be the exception.

Or maybe not so funny.
