A Caliph is a constitutional dictator, is he not?
A constitutional dictator would be less oppressive and more principled than an unconstitutional autocrat.
The Greeks also had constitutional dictators, called Archons.
A dictator is not necessarily a monarch, although a dictatorship could easily turn into a monarchy or even a dynasty.
An example of a constitutional dictatorship would be a dictatorship limited in time eg a term of office or a dictatorship that promises not to violate certain eg Koranic principles.
Surely most people would rather live under a benign dictatorship than a malign and demented matriarchy?
An example of dementia:
1) Childless old crone of a German woman saying to migrants "Come to Germany" without consulting her colleagues and then changing her mind soon afterwards, like a capricious woman who doesn't know her own mind
2) Stupid German woman's male colleagues not daring to criticise or get rid of her (because of their crisis of masculinity)
