You seem to misunderstand.

Prejudice exists throughout all people and cultures.

White Supremacy is a focused method of prejudice.

Racism is a tool of white supremacy.

Racism towards Jews, PoC, indigenous, etc. has created societal disparities.

White people are not victims of those societal disparities, and cannot be a target of racism, because again, racism is a specific tool of white supremacy.

You’re thinking of prejudice, which will never go away.

But racism can go away.
