1. He hasn't spoused actual collectivist beliefs, like "nothing out of the state, everything within the state" kind of BS (YET), just intra-race and national solidarity, so "exalts nation and often race above the individual" is argueable;
2. I don't see him promoting a supreme leader style of leadership, so "that is associated with a centralized autocratic government headed by a dictatorial leader" is not applicable;
3. I also don't see him pushing for stronger state control over the economy. If anything, he probably wants a more developmentists/startup culture economy given point 2 and 3 in (https://world.hey.com/dhh/three-sacred-cows-that-must-die-so...), so "severe economic and social regimentation and forcible suppression of opposition" is out.
Overall, he just seems like a white supremacist atm. Not every white supremacist is fascist.
