Having defended the perpetrators of the 2015 Duma arson attack in which vigilante settlers firebombed the home of a family in a Palestinian village, resulting in the deaths of a 18 month baby and its parents,[68] it was controversial that Ben-Gvir, along with Bentzi Gopstein, were seen attending the wedding of a couple related to the perpetrators, which became known as the wedding of hate, in which the weddinggoers could be seen waving rifles, guns and firebombs and even stabbing a photograph of the Palestinian toddler who was killed.
Prior to entering office Ben-Gvir was known to have a portrait in his living room of Israeli-American mass murderer Baruch Goldstein, who massacred 29 Palestinian Muslim worshipers and wounded 125 others in Hebron, in the 1994 Cave of the Patriarchs massacre; he removed the portrait in preparation for the 2020 Israeli legislative election in hope of being allowed to run on the unified right list headed by Naftali Bennett.
On 13 October 2022, Ben-Gvir took part in clashes in Sheikh Jarrah between Israeli Jewish settlers and local Palestinian residents whilst brandishing a gun, telling the police to shoot at Palestinians throwing stones at the scene, and yelling at them that "We're the landlords here, remember that, I am your landlord."[83] This was a message he later repeated in a tweet on the morning after the 2022 election in his victory tweet.
Noted Israeli sociologist Eva Illouz has said Ben-Gvir represents "Jewish fascism".
Plenty more info about him if you can stomach it.
