Author Dinesh D'Souza explained why white nationalists actually belong in the Democratic party, which promotes ethnic nationalism, just days after violence displays by white supremacists left the nation grieving.

A white supremacist rally in Charlottesville, VA turned ugly on Saturday when white racist rioters clashed with law enforcement and counter-protesters, leaving one dead and dozens injured.

"The way that the progressive Democrats have constructed their sort of multi-cultural totem pole, they encourage every form of ethnic nationalism except white nationalism," D'Souza told "Fox & Friends" on Monday. "The white guy is not welcome at the multi-cultural picnic."

Ethnic nationalism is a left-wing idea, D'Souza said.

Because of this, white nationalists really belong in the Democratic party but instead are "in a sense politically homeless because if they show up at the multi-cultural picnic they're Satan," he commented.

Many of the alt-right rioters and neo-Nazis in Virginia claimed President Trump as their leader, causing critics to compare the president to Hitler. 

Trump has never implied he wants more white immigrants, D'Souza reminded. The distinction the president has drawn is between legal and illegal immigrants.
