Antisemite means "opposing people of Semitic ethnicity". Surprisingly Arabs are also Semitic people. Therefore whichever side you pick you can't be antisemitic by definition.You can be anti Zionist and oppose people based on thier actions and ideas, not their ethnicity. I saw many people using this nonsense argument that according to a paper written by some people the definition of anti Semitism is opposing Israel. This is falsely accusing people who criticize Israel and labeling them as racist.
