Facedown Burials were Deliberate Disrespect?

A world spanning study into the phenomenon of facedown burials has concluded that they were often deliberate attempts to “disrespect or humiliate” the dead. The report I saw on National Geographic used Sweden as an example, explaining how the greatest concentration of facedown burials occurred when Christianity was spreading through the region, and may have been a way of pagans displaying their displeasure at the new religion.
