The preposterous Berlet has been hiding behind the wide skirts of powerful but gullible admins for years, getting away with murder on Wikipedia. His raison d'etre is the "anti-semitic" smear job.
The reason for this latest assault is no doubt due to the activities today on WikiQuote
http://en.wikiquote.org/wiki/WQ:VP#Using_W..._for_a_vendettaand his
own article.
Finally hoist by his own petard, people have been
adding a damning Justin Raimondo quote to his article and elsewhere, which describes Berlet for what he is, a propagandist and political hack with no scruples, who is paid to smear people. Given that Berlet has had free range from admins to smear anyone he likes on the site previously --
Quoting his own writings -- it would be hypocritical for Berlet to complain about this, wouldn't it?
As for this Brandt business, perhaps he believes Brandt is involved in the Raimondo quote pushing somehow, and is fighting back. Or else he's going on one massive WP:POINT spree. Or else, he just can't help himself, which is quite likely.
