Mokantz is wrong.

The fact of the matter is, any person who voted for Trump, whatever their reasons, voted for a man who has a long history of racism, who launched his political career with birtherism, a demagogic racist fiction, who repeatedly made racist remarks widely reported in the media, whose campaign manager and eventual senior White House advisor Steve Bannon bragged about Breitbart being a platform for the alt-right, a movement accommodating of racist ideologies, and whose candidacy met the enthusiastic approval of racist organizations like the KKK, the American Nazi Party and other white supremacist cults.

You can't hand wave all this away with peevish complaints about "extremism."
