I think "Alt right" is a label slapped on any conservative who actually walk the talk - in the hopes of smearing them with some Aryan Nation associations.
Just another liberal ad hominem to toss in their limited vocabulary - add "alt right" to racist, sexist, bigot, Christian etc
As this thread makes clear, liberals can't intellectually disseminate any issue without resorting to labels for the opposing side.
In reality, I think the so-called "alt right" couldn't unite around much other than that political correctness is destroying the west.
