I guess you should re-read your given phrase, even by the light of parent posting. We have:
"populist political philosophy, movement, or regime" > appeal to populist rethoric, check
"exalts nation above individual" > mass deportations and gov firing, "means justify the ends", check
"centralized autocratic headed by dictatorial leader" > executive orders, disregard for federal laws, DOGE, check
"economic and social regimentation" > "nationalists" vs left, woke or whatever it is this week, check
"forcible suppression of opposition" > no-process deportations, name-calling opposition, incentives to war against neighboors, check
It's all fascism MO; you probably learned fascism in school by only learning the last days and steps before WWII, not how it started.
