I’d guess it’s OWS types. Somehow I doubt that the SF losers were wearing swastika arm bands, so I bet the OWS idiots probably did beat on people in the restaurant that had nothing to do with the Stormfront folkz.
From the little that I just googled, OWS flies the anti-facist banner, and within the first page or so of results for anti-facist was the site to bring down the 'racist, facist' Rush.
No good guys in this beat down.
