The Anti Defamation League has a new report entitled "Rage Grows in America: Anti‑Government Conspiracies", which contains at least one major lie. And, it's a lie that you probably won't hear anyone else discuss, namely the one in the section about the "Birther" movement (adl.org/special_reports/rage-grows-in-America/birther-movement.asp):

Despite the fact that government officials in Hawaii and non-partisan groups have all authenticated Obama's birth certificate, the “birther” movement continues to gain adherents.

1. Government officials in Hawaii admit that they've never authenticated the picture on Obama's site that the ADL is referring to; the ADL is lying. The most any official has said is that he was born there, but she gave no further details (other than her AG-reviewed claim that he was a "natural-born American citizen"). None of that is an authentication of the only "certificate" that we've seen, and what we've seen is actually just a "Certification of Live Birth".
2. The only "non-partisan group" that claims to have seen an actual paper copy is FactCheck. As can be seen at the link, they aren't a credible organization and they certainly don't act too very "non-partisan". The most other organizations claim to have seen is what we've all seen: pictures. And, the persons from Fact Check who claim to have seen the document were just their - per them - "staffers"; they didn't call in document experts. Several other issues with the Fact Check "authentication" are listed here; note that Fact Check falsely claimed that Hawaiian officials had said he was born there since November of last year, when in fact the statement from those officials was ambiguous, with the ambiguity only being resolved in late July of this year. In other words, Fact Check lied to their readers for around nine months.

There's more, with the ADL featuring sections on Philip Berg, Orly Taitz, and Jerome Corsi. Of the first, they say in part:

According to one report, Berg’s suit alleged that the World Trade Center was actually destroyed from within and that FEMA actually had a plan in place that would replace elected officials with a secret government.

If you read the complaint (rodriguezlawsuit.googlepages.com), you'll find some wacky claims. However, FEMA does have plans for continuity of government; that's widely known such as from the Iran-Contra hearings. Whether, as the complaint claims, they wanted to replace the current government with a "shadow government" is another matter, but the ADL isn't doing themselves any favors by not referencing things like the "REX 84" program.

Of Corsi, they state:

In October 2008, the Kenyan government expelled Corsi, who had traveled to the country both to promote his book and to investigate alleged ties between Obama and Kenyan Prime Minister Raila Odinga.

He wasn't just "expelled"; he was expelled for political reasons. The ADL is implicitly siding with the little fascists who cheered Kenya's actions.
