It wasn’t though, was it. The IDF are not Jews in general; they are multi-ethnic and are the armed forces of a country at war. Would a chant of “death to the Russian Armed Forces” be Russophobic? “Death to the Wehrmacht” for anti-German during World War 2? “Death to Hamas” for Islamophobia?
Identification of the armed forces of a state with a state is a sign of fascism, and the identification of the state with an ethnic group is a sign of extreme nationalism - though admittedly that is less the case with Israel and Jewish people.
Chanting “death, death to the IDF” is violent and inappropriate at a music festival. “Fuck the IDF” would’ve been fine though.
Not convinced this really belongs in Technology; he was inciting violence and would expect to be convicted on whatever medium.
