Things didn't go quite as planned for a group of anti-Israel activists, who hoped to force the closure of an Israeli-owned shop in honor of "Nakba Day" - the day dedicated to mourning the failure of combined Arab armies to destroy the State of Israel at birth.
Several dozen members of the London Palestine Action organization targeted the Sabon cosmetics store on Sunday, mimicking campaigns by other anti-Israel boycotters - belonging to the so-called Boycott Divestment and Sanctions movement (BDS) - to force the closure of businesses owned by Jewish Israelis.
Among them was a Pamela Hardyment, a pro-Palestinian campaigner notorious for her vicious anti-Semitic invective.
But they weren't prepared for the response by pro-Israel activists, who turned the tables on the BDS flash mob.
Having learned of the event via social media, the Israel Advocacy Movement mobilized far more activists - including a number of pro-Israel Muslims - seriously outnumbering the bewildered group of far-left and Islamist extremists.
Adding insult to injury, the pro-Israel campaigners used the opportunity to food the Israeli shop with customers, defying the drowned-out calls for a boycott.
On its Facebook page, the IAM sent a message to London Palestine Action:
"London Palestine Action tried to close down an Israeli cosmetics shop in London called Sabon, their reason? Because the Sabon factory is in Kiryat Gat, a city well within the 1949 Armistice Lines, this was not a protest against "settlements", disgracefully this was a protest against the very existence of Israel.
"London Palestine Action promoted this event for over a month, yet without advertising we were able to mobilise far more activists than they had. For one of the first times in years, our chants of "1, 2, 3, 4 stop the boycott, stop the war, 5, 6, 7, 8 stop the boycott, stop the hate", drowned out their screams of "From the river to the sea, Palestine will be free"... a call for the destruction of Israel."
In another post, the group added:
"London Palestine Action your antisemitic actions are not welcome on British streets. No longer will we tolerate your thugs intimidating Jewish businesses, every time you persecute our people, we will respond in numbers until you end your bigoted persecution of Jews and Israelis."
