Is "Alt Right" the Same as "Fascist"?

I am using the term fascist advisedly, not as a general term of political abuse.

Wikipedia says alt right is "associated with white nationalism,^[1][2][7] white supremacism,^[3][8][9] antisemitism,^[1][2][10] right-wing populism,^[7] nativism,^[11] and the neoreactionary movement.^[8][12]"

Is that not the summary of fascism?

I do not think Donald Trump is a fascist, because I do not think he has many specific ideological convictions.  But he certainly has mobilized and encouraged white nationalist nativists in a way they have not had a public voice since the George Wallace campaign.
