The so-called 'alt-right' is actually white nationalism. This extension replaces mentions of 'alt-right' with more accurate terms.
There's nothing new about the "alt-right" movement -- it is essentially white nationalism and white supremacy. The mainstream media continues to use the phrase "alt-right" instead of calling it what it is.
This extension replaces mentions of the phase "alt-right" (and "alt right") with either "white nationalism movement" or "white supremacy movement".
