In the news video (in Polish - sorry), you will see a small group protesters, standing near the wall, not bothering anybody, holding a large sign that reads "Stop the butchery in Gaza", and then the "Anarchists Organization" symbol painted at the end of the sign.
You will see a man in a yarmulka get up from his chair, walk all the way across the room, and start to swing punches at the surprised protesters. Poland is a civilized country, after all, and while things like that happen, they tend to at soccer matches between hooligans, not in an official function with an Israeli ambassador with lots of cameras present.
This is not Israel where women are stoned by fanatical Orthodox Jews for wearing red color clothes (MSNBC article).
It looks like it is OK to beat up a woman with your manly, macho fists if the woman is a goy...
The funny bit is that the reporter says that unfortunately, the assailant was unidentified (!) and that three anarchists were held over by the police (double !!).
"Alicja Krobus (sp?), the president of the Poznan's Jewish region (gmina) could not identify the man". (Triple !!!).
So, summation: protesters arrested and held over by the police, the Jewish man who beat them up - no consequences, off to beat up other women somewhere else, possibly with no cameras around.
Aha, also mainstream polish press (and soon to follow, I assume, world media): Jewish man beat up in Poland by anarchists.
Irony Overload Alert!
Read the following at your own risk!
The official function was a concert gala (very high class, very fancy schmancy). It was a Righteous among the Nations award ceremony, a title which is the highest honor Israel can give a non-Jew (wikipedia entry here).
When Yad Vashem, the Holocaust Martyrs' and Heroes' Remembrance Authority, was established in 1953 by the Knesset, one of its tasks was to commemorate the "Righteous among the Nations". The Righteous were defined as non-Jews who risked their lives to save Jews during the Holocaust.
I wonder if the Palestinians have a similar award (and if not, perhaps they should establish one very quickly?).
You know, something like "Rightous non-Moslems who saved Palestinians from Israeli white phosphorus" (working version - come up with something better, Gazans).
