I never mentioned anything about referenda. Popular opinion in those countries is they are largely happy enough with their monarchy.

From what I can tell, in Norway it does seem that things have changed only a little bit.

Note I'm not a particular fan of any monarchy, but you did state that "I think the vast majority of people in any country would prefer a Head of State that is chosen by popular vote rather than by Royal Sperm." That's an easily falsifiable statement.
