The term Alt Right has lost all meaning at this time. It is just a term used by some to denigrate those with opinions with which they disagree.
Agreed to an extent. Racists exist (in all colors too), but the LW has overused the word so much it is as diluted as pissing in the ocean. It's now meaningless since, whenever a RW suggests anything against Obama, the poor, etc, they are immediately labeled a racist. After years of this, the Right stopped caring and the word lost meaning.
The LW is doing exactly the same thing with "alt right". Yes, "Alt Right" conspiracy nutjob white supremacists exist, but by labeling anyone on the right as a member of the "Alt Right", again the word/phrase is losing meaning.
