Why do people conflate anti-Zionism with antisemitism?

What Israel is doing to Palestinian civilians is wrong, so many babies, women, and children have died and are suffering. Netanyahu is extremely right wing and only cares about power. People need to understand that Zionism in it's current form is wrong and I cannot in good question support something like that. As an American Jew, it's mind-blowing to me that people can support this kind of stuff after everything that happened in the Holocaust.

I believe that all people are equal and everyone deserves the same human rights regardless of race, gender, religion, sexuality, nationality, ethnicity, disabilities, etc...
