In the past, there have been reports of tensions between religious groups in Israel, with some incidents of violence and vandalism targeting Christian and Muslim holy sites.
Protecting Holy Land Christians tracks violence against christians, and they corroborate the claim that the attacks have risen
Some critics argue that the far-right elements in Israeli politics, including those associated with former Prime Minister Benjamin Netanyahu, have created an environment that encourages such incidents. However, it is difficult to definitively prove a direct correlation between any specific political coalition and an increase in violence against a particular religious group.
I would classify the claim as "Exaggerated/Misleading," because although there may be some truth to the assertion that far-right elements in Israeli politics contribute to tensions between religious groups, it is not accurate to say that violence against Christians is being "normalized" under any specific political leadership.
