Southern Povery Law Center on Breitbart:

Since its founding in 2007, Breitbart News Network has grown to become one of the most popular news outlets on the right. 

Over the past year however, the outlet has undergone a noticeable shift toward embracing ideas on the extremist fringe of the conservative right. Racist ideas. Anti-Muslim and anti-immigrant ideas –– all key tenets making up an emerging racist ideology known as the “Alt-Right.”

The Alt-Right is a loose set of far-right ideologies at the core of which is a belief that “white identity” is under attack through policies prioritizing multiculturalism, political correctness and social justice and must be preserved, usually through white-identified online communities and physical ethno-states.
