Anti-Zionism is antisemitism because by the exact definition includes the Jewish peoples indigenous roots to the land of Israel over hundreds and thousands of years.
Moreover. Zionism makes clear that Jewish people are an ethnicity or national origin—similar to Hispanics and Asians—Jews are NOT a race!
This means the textbook definition of genocide preached by Anti-Israel and Pro-Palestinian groups is not applicable to Israeli Jews because they are, in fact, NOT a race of people (which is either Black or White as clearly defined by the US Government, Census Bureau and OMB—where I once worked).
