Get “Alt right” out of your vocabulary. It is a way of referring to white supremacist groups that obscures the reality of what they are. Think about the framing: “alt” means alternative, as if it’s just another way of being on the right. It also suggests it’s trendy or cool -like “alt country”. However, it’s not a benign alternative and it’s definitely not cool.
Organized racism is extremely dangerous. It has grown tremendously in recent decades as Republicans have tolerated and even courted racist votes. Racists now feel emboldened to come out of the shadows as candidate Trump made racism a central theme of his campaign and as President Elect Trump named a prominent white supremacist as his closest presidential adviser.
We should never use this term and neither should the media. For at least half a century they’ve properly used the term “white supremacists” and have only recently switched. Some media outlets are now reconsidering the term alt right and are drawing guidelines for it’s use -it’s our duty to encourage them to drop it entirely; nothing less than it’s abandonment is appropriate.
As a general rule, call things what they are. Softening or using euphemisms as rhetorical courtesy often obscures reality. Don’t make it harder for your listeners to know exactly what you mean.
