Zionists first claim that they represent Jews as a whole. Then naturally if you oppose Zionism, you hate Jews. This is called circular reasoning and is not valid. Likewise, a serial killer might claim that he represents all people of some minority on the planet, therefore if you apprehend him, you are persecuting the said minority.

Zionists have no right to lay a claim over Jewishness or Jewry or Judaism.
What IS really antisemitic, is Zionism itself that is based on two antisemitic tropes: 1) that Jews are a race, a people, and 2) that Jews are so different from the rest of humanity that they must be forever separated from other people (in The Jewish State), otherwise there will never be peace because there is no way Jews can live among non-Jews like all other groups live alongside each other.
Zionists have always hated Jews who refused to segregate this way. The first assassination that Jewish terrorists in Palestine have committed, was to kill JEWISH federationist (the one who struggled to create an independent state in Palestine that would include wishing to immigrate European religious Jews on equal terms with Palestinian population) Jaacob Israel De Haan.

Disregard for Jewish lives and readiness to dispense of non-Zionist Jews have always been a typical feature of Zionism.
«The hopes of Europe’s […] Jews are centered on emigration. I was asked, ‘Can you bring six million Jews to Palestine? ‘I replied, ‘No’….From the depths of the tragedy I want to save two million young people…The old ones will pass. They will bear their fate or they will not. They were dust, economic and moral dust in a cruel world…Only the branch of the young shall survive…They have to accept it.»
(Chaim Weizmann reporting to the Zionist Congress in 1937 on his July testimony before the Peel Commission in London)
“Only through blood (of the Jews in the Diaspora) will the land be ours”: Nathan Schwalb, Jewish Agency representative in Switzerland.
«If we do not admit the rightfulness of antisemitism, we deny the rightfulness of our own nationalism. If our people is deserving and willing to live its own national life, then it is an alien body thrust into the nations among whom it lives, an alien body that insists on its own distinctive identity, reducing the domain of their life. It is right, therefore, that they should fight against us for their national integrity.»
