I still don't understand why "aggressively anti-socialist" policies are fascist. Fascism is itself a branch of socialism (Mussolini was one, in France the fascist leader Jacques Doriot was one as well, for instance). Being a totalitarism, it aims at engulfing every aspect of the daily life, which means supporting socialist policies (similar to communism, another totalitarism).
Authoritarian regimes in the 30´s that were "aggressively anti-socialist" weren't fascist. Franco or Salazar are relevant examples, even thought today they would be categorized as such, since you guys seem now to have only single word left to designate populist or authoritarian regimes then don't like.
Trump lacks deeply indeed the socialist aspect of fascism; it would likely be better defined as plutocratic cesarism, even though he did not make a coup (yet).
