People are completely horrified by this 'Hail Trump' video

A video published on The Atlantic that shows Richard B. Spencer -- founder and ideologue of the "alt-right" movement -- shouting "Hail Trump, hail our people, hail victory" has caused heated reaction on social media.

Spencer's salute to the crowd of more than 200 people, who gathered for the annual conference of the far-right National Policy Institute in Washington, D.C., was met by Nazi salutes and cheers.

Earlier, Spencer railed against Jews and made several Nazi references during his speech, using the slur “Lügenpresse” -- a word originally employed by the Nazis -- to attack the mainstream media.

“America was until this past generation a white country designed for ourselves and our posterity,” Spencer said. “It is our creation, it is our inheritance, and it belongs to us.”   

Many on Twitter said they were disturbed by the numerous Nazi references in the video:

The Holocaust museum issued a strong condemnation of the conference. "The Holocaust did not begin with killing; it began with words," they said in a statement:
