Actually it's yet another false media creation.Alt Right is a white supremacist movement!
Bannon is on record saying so.
Bannon once described Breitbart News in an interview with the Investigative Fund as the "platform for the alt-right," or alternative right. It's a brand of far-right conservatism that generally embraces and promotes white nationalism, racism, anti-Semitism, homophobia, transphobia and misogyny.
The Alt-Right is Islam.
