So many people think Trump is a fascist that an official wikipedia page has been created.
https://en.wikipedia.org/wiki/Donald_Trump_and_fascism
Trump has supported political violence against opponents; many academics cited Trump's involvement in the January 6 United States Capitol attack as an example of fascism. Trump has been accused of racism and xenophobia in regards to his rhetoric around illegal immigrants and his policies of mass deportation and family separation. Trump has a large, dedicated following sometimes referred to as a cult of personality. Trump and his allies' rhetoric and authoritarian tendencies, especially during his second term, have been compared to previous fascist leaders. Some scholars have instead found Trump to be more of an authoritarian populist, a far-right populist, a nationalist, or a different ideology.
An October 2024 poll held by ABC News and Ipsos indicated that of the candidates in the 2024 United States presidential election, 49% of registered voters considered Trump to be a fascist.
