Likud MK Oren Hazan blamed Education Minister Naftali Bennett (Jewish Home) for the anti-IDF exhibit at the Herzliya Gymnasium.
"Once upon a time, there was an amazing Zionist school called the 'Hebrew Gymnasium of Herzliya.' It was the first Hebrew-language high school in the world! That's what we used to have," Hazan wrote. "What we have today is a principal who tries to poison the students' minds with clear anti-Zionist messages.
"But you know what? I don't blame him - that's his ideology. I blame Education Minister Naftali Bennett, who has allowed this embarrassment to happen under his watch, time after time, instead of sending this principal to a school in Ramallah.
"Bennett, forget your speeches - do something. This craziness has got to stop!!"
On Sunday, Hazan joined MK Oded Forer (Yisrael Beytenu) in a protest outside the Gymnasium, after Gymnasium students presented an exhibit featuring IDF "soldiers" abusing an elderly Arab.
