Narrow Community. Political science and adjacent disciplines

This is not unique to fascism. Any totalitarian regime value collective more than the individual.

To have a strategy you need strategic thinking. I'm not sure this is the case in your example.

Definitely

Probably

You're spot on. Fascism and communism are at their core extremely similar ideologies. It all comes down to how you define your "tribe". In fascism this is defined by race, ethnicity, and religion, whereas for communism this is defined by class. Both ideologies favor populism, in that the good of the "tribe" is more important than the good of the individual, and if you're not in the "tribe" then you can get fucked. And both ideologies view the tribe as infallible in so far as that anything wrong in society must be the result of outside influence. I'd recommend looking into the work of Yuval Noah Harari, he's written a lot of very insightful books on these topics.

I got this idea from Wikipedia:

Racism was a key feature of German fascism, for which the Holocaust was a high priority. According to The Historiography of Genocide, "In dealing with the Holocaust, it is the consensus of historians that Nazi Germany targeted Jews as a race, not as a religious group."[56] Umberto Eco,[39] Kevin Passmore,[57] John Weiss,[58][page needed] Ian Adams,[59][page needed] and Moyra Grant[60] stress racism as a characteristic component of German fascism. Historian Robert Soucy stated that "Hitler envisioned the ideal German society as a Volksgemeinschaft, a racially unified and hierarchically organized body in which the interests of individuals would be strictly subordinate to those of the nation, or Volk."[61] Kershaw noted that common factors of fascism included "the 'cleansing' of all those deemed not to belong – foreigners, ethnic minorities, 'undesirables'" and belief in its own nation's superiority, even if it was not biological racism like in Nazism.[45]
