They are fighting an alleged "culture war" and also call it that way. I also think that Trump's movement is very spiritual, almost like a cult.
Anyway, all I'm saying is that based on common criteria the term Fascism is adequate for Trump's movement. I'm not claiming that it's strongly related to prior Fascist movements. These occurred in other countries at other times and I leave it to scholars to make comparisons if they must.
And then the cult of traditionalism while strong in the NRx movement, is arguably stronger in the Republican side than in MAGA itself.
Ultimately Fascism is deeply spiritual but all I get from Trump is brash 80's boomerism. He's not ideological enough.
