Why be nice about it. They’re Nazi Socialists and what they are spewing is no different than what Hitler and his party was saying in the 20th century.
Adbusters may have some anti-semitic members, or just members that are opposed to Israeli policy, or just naive about the way the world works.
But even if adbusters was 100% anti-semitic, they are only one of the groups using OWS to make a case for their causes.
There are a bunch of liberal Jews, and probably a few libertarian Jews, attending these OWS meetings. And none of the ones I know are self-hating Jews or anti-semitic.
Do we have to sink to the same low tactics that the MSM and the Democrats use to defame the Tea Partiers?
Unfortunately the answer on FR seems to be a most emphatic "Yes we must!"
