The ADL's complaint about Bannon is thin gruel: http://www.adl.org/sp/stephen-bannon-backgrounder/bannon-bac...
It boils down to their claim the Alt Right is anti-Semitic, when that's only the small portion of it that's the Alt White vs. the vastly larger Alt West and even larger Alt Lite which isn't there yet, plus our rule that we don't shoot at people who are shooting in the right direction (which, come to think of it, has not as of late characterized the Alt White), Breitbart.com is not an entirely polite or Leftist publication, "Bannon is a Critic of the Republican Establishment and the Left." (a truly devastating charge, how dare he!), "Bannon has Held a Number of Positions in his Career." (the gravamen of that is they weren't on the Left), and they bury the lede by ending with "We Are Not Aware of Any Anti-Semitic Statements From Bannon." (even they are not willing to take his ex-wife's claims from their 2007 divorce as credible).
Seriously, the establishment, remarkably excluding the GOPe, has gone all in on smearing the next Republican Karl Rove figure with abject lies even the ADL can't defend face-to-face, and our response is "We Don't Care". As I've commented here before, that the GOPe is included in the "we" should and I suspect does terrify the Left, they're rapidly losing one of their potent weapons short of lawfare.
