If you've never done so, you might go to the Breitbart article linked earlier that was about Bill Kristol.

And then read the comments. If you do, you'll understand why people aren't calling him a voice of the alt-right or a white nationalist or anti-Semite just because of what might have been said in a divorce. It's clear Breitbart welcomes anti-Semites and white nationalists. People who worked there for Bannon make similar claims about Bannon. He's never denied being a voice for the alt-right, and has in fact claimed proudly he's a voice of the alt-right. All he does is deny that the movement itself is anti-Semitic, or racist, or white nationalist, but obviously embraces the 'nationalist' part. So then go read a few alt-right outlets and judge for yourself whether the movement is white nationalist or not.
Who knows whether or not Bannon is personally anti-Semitic, or whether he just hates all liberals, and there are lots of Jewish liberals. The problem is he's never given any indication that he cares whether the alt-right movement is 'shot through' with white nationalists.
