Ethnic nationalism is just racism, whether practiced by white supremacist MAGA Americans or Holocaust survivors. In a liberal democracy, the government serves all people regardless of race. I'm confused by your premise that Holocaust survivors were entitled to their own ethnic state for some reason.
Also, the Zionist movement was not a response to the Holocaust. It was a colonial enterprise that began well before the Holocaust in response to widespread persecution especially in Central Europe. Many Jews opposed the Jewish nationalism undergirding Zionism for the same reasons liberals today reject virtually all nationalist movements. Many emigrated to liberal democracies like the United States where they could live free of ethnic discrimination. Zionists instead chose to respond with their own ethnic persecution.
It is worth recalling in this connection that at the turn of the century,
Zionism's similarities to other projects of colonization were not a source of
embarrassment or shame for most of the movement's adherents; indeed, they
often saw them as a selling point. Zionist leaders studied and sought to learn
from the experience of European colonial-settlement enterprises in places like
Algeria, Rhodesia, and Kenya, and many imagined their own endeavor as
similar in certain ways. Moreover, the Zionist movement readily used such
terms as “colony,” “colonial,” and “colonization” to refer to its activities; thus,
for example, the original name of its financial arm was the Jewish Colonial
Trust. It was only later, after the First World War, that colonialism came to
have strongly pejorative connotations for many Europeans. As a consequence
the Zionist movement sought to dissociate itself from other European projects
of colonization and settlement, began to stress the uniqueness and noncolonial
character of its mission and methods, and stopped using such terms, at least
in languages other than Hebrew.

I mean OP called Sanders anti-Zionist. He's certainly not that. Bernie has also outright stated that he supports Israel. I will admit that I may be slightly overstating the case to say that he's incontrovertibly a Zionist, but he at least may be from his public statements.
The key phrase is "as a Jewish state" which is what it is. It's declaration of independence states as much.
The term Jewish state has been in common usage in the media since the establishment of Israel, and the term has also been used interchangeably with Israel. George W. Bush used the term in his speeches and in an exchange of letters with Israeli prime minister Ariel Sharon in 2004.[5]Barack Obama has also used the phrase, for instance in a speech in September 2010 to the United Nations General Assembly.[6] The Israeli government under prime minister Ehud Olmert made the recognition of Israel as a Jewish state by the State of Palestine a pre-condition in the peace negotiations,[7] as did the government of his successor, Benjamin Netanyahu. (Wikipedia)
The concept of a national homeland for the Jewish people is enshrined in Israeli national policy and reflected in many of Israel's public and national institutions. The concept was adopted in the Israeli Declaration of Independence on 14 May 1948 as the objective of the establishment of modern Israel. The principle was given legal effect in the Law of Return, which was passed by the Knesset on 5 July 1950, and stated: "Every Jew has the right to come to this country as an oleh."[17] (Wikipedia)
A central issue in the Israel-Palestine debate is the Right of Return:
Opponents of the right of return hold that it is an unrealistic demand with no basis in international law and that if Israel were to absorb approximately five million Palestinians with an already existing large Arab population, it would lead to the demise of the Jewish state.[8]
So yes, opponents of Zionism call for the abolition of Israel as a Jewish state and the formation of a egalitarian state for all people regardless of race, ethnicity, or creed or at the least the creation of an independent Palestinian state to exist alongside Israel. But anti-Zionists do not support the Israel of today which is explicitly a Jewish ethno-state.
Go ahead and describe what exactly he should have done to make an effective protest. In the meantime, consider that perhaps he simply did not want to be a cog in a genocidal machine as he clearly stated.
