I find that video to be in extremely poor taste (I didn't watch it) however, The Knights Templar would spit on the cross, not as a mockery of Jesus but rather as a mockery of the falsehood of the Crucifixion. It was really Jacques De Molay who was crucified in a doorway, by the church, before being burned at the stake... Hence why The Turn Shroud has AB- blood, relating to our earlier estimation this bloodtype was created via Cleopatra and Caesar.
