You can’t blame the victims for racism. The whole point of racism is that it lumps people together based on the actions of some.
It’s the same way Islamophobia doesn’t become justified based on the actions of some Muslims.
Anyone who does do that is already a bigot, and would do the same to any other group, regardless of what they do.
A culture that normalizes hatred of Jews (or Israelis) as a group, will very quickly devolve into one where other minorities are hated as well. Because the youth, as gullible as they are, can still detect when a system of values is inconsistent.
