I personally favor the features of "Ur-Fascism" by Umberto Eco:

1. cult of tradition

2. rejection of modernism

3. action for action’s sake

4. disagreement is treason

5. fear of difference

6. appeal to a frustrated middle class

7. obsession with a plot

8. the enemies are at the same time too strong and too weak.

9. pacifism is trafficking with the enemy.

10. contempt for the weak

11. everybody is educated to become a hero

12. machismo - both disdain for women and intolerance and condemnation of nonstandard sexual habits, from chastity to homosexuality,[...] Since even sex is a difficult game to play, the Ur-Fascist hero tends to play with weapons

13. selective populism

14. Newspeak

These are only his major points of his speach in 1995. The speach is at the moment available here: https://www.nybooks.com/articles/1995/06/22/ur-fascism/
