There is a segment of Jews in Israel that are racist, like exist in all groups including Palestinians, but Israel has nothing to do with “white supremacy”. Even the Nazis had nothing to do it with “white supremacy”. They were German supremacists. They happily murdered millions of other people with white skin including millions of Jews with white skin.
Other than a tiny minority of kooks in some heavily mixed countries whose only identity is ridiculously “whiteness” (whatever that means) there is no such thing as”white supremacy”. The overwhelming number of people in the world with white skin don’t have a white identity. It’s not Jim Crow or slavery era. It’s not like some black people in the US that organize around their color. There is no white history month. There is no white music awards. There is no white scholarships. People with white skin have a variety of ethnic and national identities. It’s like trying to lump in Chinese, Japanese and Koreans as as ‘Asian supremacists”. “White supremacy” is usually code words for leftist smear tactic or racism towards people with white skin.
