Yair Netanyahu, the son of Prime Minister Benjamin Netanyahu, waded into the controversy over the Jewish nation-state law and blasted the “Bolshevik” leftists in a social media post overnight Sunday.

“The nastiness of the left-wing ‘Bolsheviks’ labeling of the right (which is the real liberal camp in Israel) as ‘Nazis’ and ‘fascists’ is nothing new,” Netanyahu wrote on Facebook and Twitter.

“After all, they also called Ze’ev Jabotinsky ‘Vladimir Hitler,’” he added, referring to the pre-state founder of Revisionist Zionism.

His comments came as opposition to the law continued to mount. An estimated 50,000-plus people, waving Israeli and Druze flags and calling for equality, gathered at Tel Aviv’s Rabin Square on Saturday night to demonstrate against the controversial legislation, derided as discriminatory towards the country’s non-Jews.

The nation-state bill — which for the first time enshrines Israel as “the national home of the Jewish people” and says “the right to exercise national self-determination in the State of Israel is unique to the Jewish people” — has sparked widespread criticism from Israel’s minorities, the international community and Jewish groups abroad.

There was no official response by the Netanyahu family, but following previous incidents a spokesperson has stressed that Yair Netanyahu is a private individual and can say what he wants on social media.

He has previously provoked controversy with his social media posts, most recently sharing an image saying “Fu*k Turkey” on Instagram.

Last year, the younger Netanyahu sparked anger by posting a cartoon on Facebook widely derided as having anti-Semitic themes.

The cartoon, with references to Jewish billionaire and philanthropist George Soros, the Illuminati and some sort of lizard creature, took aim at his parents’ critics in a series of corruption scandals, alleging they were part of a conspiracy.

He subsequently removed that post.
