I think the problem with islam comes from getting people together for a stoning. When everyone throws from the right side it all works out but if you get a couple of lefties in there it would fuck up the fall of the rocks. People would be worried about catching an errant elbow from the guy next to them.
Catholicism has the same problem only it derives from Bingo games.
