If you really believe that a bookcase is a symbol of Christianity, then you need help my friend....
I have accepted that some people cannot see the obvious, and that the shot was intentionally manipulated to insert the Cross using the "accidental" bookcase in the background. I am not sure how they can not see it, but they maintain that they can not, and I have no choice but to accept that.
It is abundantly clear to me, though. And now the Huckabee supporters are trying to stir up trouble between religious folks and secular society in order to cover his butt. It reminds me of the times when another Arkansas huckster threw Thomas Jefferson, FDR and Martin Luther King Jr. down the stairs by bringing up their marital infidelities in order to protect himself from his own discretions.
Some folks are willing to do any amount of damage in order to advance themselves. We don't need another man like that in the White House.
