Carl not so long ago there was a similar theory about Catholics. It was said that because they followed the Pope who is like a king Catholics could not become democrats. This was once used in a theory to explain why there were so many dictatorships in Latin America. The argument went that because they were Catholics they always gravitated towards a Jefe, strongman because they followed the Pope. In fact that was also an argument against the election of John Kennedy. There was a political cartoon against him that said if elected there would be a tunnel from the White House to Vatican City and Kennedy would be taking direct orders from the Pope.
