Israeli politicians were aghast following a Channel 10 report Wednesday night of Jewish extremists dancing at a wedding while cheering the murder of a Palestinian family in Duma and calling for more killings.The one minute long video showed young men wearing white skullcaps and shirts dancing while holding knives and guns. One of the dancers stabbed a photograph of a slain Palestinian toddler Ali Dawabsha. Another young man was held aloft as he clutched a molotov cocktail in one hand and a knife in another.Politicians from across the political spectrum, including Prime Minister Benjamin Netanyahu, immediately condemned the video.“The shocking pictures that were broadcast this evening show the true face of a group that constitutes a danger to Israeli society and to the security of Israel. We are not prepared to accept people who deny the laws of the state and do not view themselves as subject to them. The pictures underscore how important a strong ISA is to the security of us all,” Netanyahu said.Yesh Atid head Yair Lapid said, “These people are a danger to the state of Israel. We must fight them, the way we fight Hamas and Hezbollah."“These people did not spring up out of a void. There are rabbis, ideologues and politicians behind them,” Lapid said.MK Bezalel Smotrich (Bayit Yehudi) said, “The evil ideology of price tag attacks has no place in religious Zionism, period. Anyone who doesn’t understand this should look at the video that was published on Channel 10.”“That kind of twisted dancing with pictures of a baby who was murdered in his sleep reflects a dangerous ideology that has lost all traces of humanity,” Smotrich said.Such an ideology, he added has no place in the world of religious Zionism and is not a legitimate part of the dialogue in the democratic state of Israel.
