The NFL God is a Christian god.
"When Kansas City Chiefs safety Husain Abdullah intercepted a Tom Brady pass and returned it for a touchdown Monday night, he did what so many other NFL players do to celebrate a big play: He paused to make a religious gesture of thanks. But Abdullah, a devout Muslim, found that his religious display was met with less latitude than, say, Tim Tebow when he brought Tebowing into the NFL. Abdullah was penalized 15 yards for unsportsmanlike conduct because he slid to the ground, then knelt in in the end zone.”
Under this new precedent, every sign of the cross deserves a penalty.
