Are there any similarities between ethnocratic and fascist ideologies and can you name any examples of ethnocratic and fascist regimes in our modern history ?

The Zionist state.
Oren Yiftachel defines Israel as an ethnocracy rather than a democracy. According to Yiftachel ethnocratic regimes:

“…promote the expansion of the dominant group in contested territory and its domination of power structures while maintaining a democratic facade.”

Ethnocracies have several distinguishing characteristics:
  • Despite declaring the regime as democratic, ethnicity (and not territorial citizenship) is the main determinant of the allocation of rights, powers, and resources, and politics is characterized by constant democratic-ethnocratic tension.
  • State borders and political boundaries are fuzzy: there is no clear demos, mainly owing to the active role of ethnic diasporas and the bounded, unequal citizenship of ethnic minorities.
  • A dominant, “charter” ethnoclass appropriates the state apparatus and determines the outcome of most public policies.
  • Segregation and stratification occur on two main levels: ethnonations and ethnoclasses.
  • The socioeconomic sphere is marked by long-term ethnoclass stratification.
  • The logic of ethnic segregation is diffused into the social’ and political system, enhancing multidirectional processes of essentializing political ethnicization.
  • Significant (though partied) civil and political rights are extended, to members of the minority ethnonation, distinguishing -ethnocracies from Herrenvolk (apartheid) or authoritarian regimes.
Sounds familiar?
But unfortunately, it doesn’t stop there. All of the above applies only to so called “Israel proper”, meaning we are completely neglecting the areas beyond the green line that Israel is expanding into and controlling. If we look at the entirety of the territory controlled by Israel, ethnocracy would be too toothless of a term to describe the complex system of IDs and tiered ethnicity-based rights employed by Israel. This system finally pushed B’Tselem, Israel’s largest human rights group to officially designate Israel as an Apartheid state.
