Many diverse regimes have self-identified as fascist and therefore the defining of fascism is more complicated and contentious than you are implying.
Historians, political scientists, and other scholars have engaged in this very debate. The debate concerning the exact nature of fascism and its core tenets has still not completed and is therefore more complicated than you are pretending that it is by assuming one definition and adjusting all other remarks around that one definition.
Mirriam-Webster defines fascism as:
"a political philosophy, movement, or regime (as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition"[1].
It is not hard to expand this to include religion as well as "race", each are equally social constructs and create well-defined lines. The nation that they exalt above the individual is clearly the caliphate...
One thing to particularly note, although this group does promote world expansion, it is not necessary to be fascist to also be Empire Builders...
Now another definition, a more recent one from a political scientist:
"Fascism may be defined as a form of political behavior marked by obsessive preoccupation with community decline, humiliation, or victim-hood and by compensatory cults of unity, energy, and purity, in which a mass-based party of committed nationalist militants, working in uneasy but effective collaboration with traditional elites, abandons democratic liberties and pursues with redemptive violence and without ethical or legal restraints goals of internal cleansing and external expansion." - Robert O. Paxton
This one also fits if one concerns themselves with the fact that a Theocratic government is also a political movement and that centralizing it and expanding it throughout even just the Muslim world fits the expansionist nature of the movement....
We'll begin there.
Do you recognize that even the OED is not the definitive defining factor for a term argued over decades that as yet has not real solid agreed-upon definition among political scientists? Do you recognize that by the definitions of the scholar I quoted and the dictionary, as well as even the OED, coupled with my perspective can easily fit this ideology into fascism?
