What I have seen is a confusion (perhaps intentional) between anti-semitism, and protesting Israel’s behavior since the Hamas attack in October.
Criticizing Israel’s response is not anti-Semitism- it is literally just criticizing the response.
Of course, a lot of criticism of Israel is rooted in antisemitism. But saying all criticism of Israel is antisemitic deflects legitimate criticism, and makes it harder to identify legitimate antisemitism.
Who is saying this? All I've heard are people on one side insisting that people are saying this, sounds like a straw man

This is not the same as being critical of that state, being anti-Israel isn't antisemitic (except when it is, obviously), but nor is it anti-Zionism. Saying Netanyahu should be dragged before the Hague, that the international community should demand an immediate ceasefire or force a two-state solution, that Israel must uphold the right of return: none of these are anti-Zionism, nor antisemitic.
If your position is not that Israel must be destroyed, good, don't call yourself anti-Zionist though. If it is, then yes, that's antisemitic, or the word is meaningless.
Similarly, find another slogan besides "From the river to the sea", because that is, in fact, a call to ethnically cleanse all Jews from Israel. It has meant that since the establishment of Israel, and you don't get to wander in and say it means something different at this point. If you don't mean that, don't say it. Find literally any other way to express yourself.
That’s not true. Rebbe Teitelbaum was an anti-Zionist, he opposed the creation of the modern state of Israel as sinful, and he opposed Haredi Jews cooperating with the state (such as by being elected to the Knesset or accepting government benefits.) But he did not support the physical destruction of Jewish communities in Eretz Yisrael. And that remains to this day the mainstream anti-Zionist position of Satmar, Edah HaChareidis in Israel, and the Central Rabbinical Congress in North America - the belief that the existence of the state of Israel is a sin, and that it is a sin for Jews to cooperate with it, but at the same time strongly condemning extremist anti-Zionist groups such as Neturei Karta who ally with non-Jews who seek to physically harm Jews who live there, and rejecting any cooperation with the Palestinian cause-Rebbe Teitelbaum viewed his anti-Zionism as an internal Jewish issue, and in any violent conflict between Jews and non-Jews he would pray for the Jewish side, even though those Jews happened to be his Zionist opponents.
As well as mainstream Haredi anti-Zionism, there are other varieties of anti-Zionism which don’t entail support for the physical destruction of Israel. Zionism is Jewish nationalism. Some people have a principled ideological opposition to all forms of nationalism - they are anti-nationalists - and a consistent anti-nationalist must also be an anti-Zionist. That principled opposition to all nationalist ideologies does not entail any particular position on practical questions, and is completely compatible with pacifism, and hoping that the majority of the population of Israel/Palestine eventually comes to peacefully reject nationalism.
Nationalism comes in many varieties - civic, linguistic, ethnic, religious, ethnoreligious, etc - and Zionism is a nationalism of the ethnoreligious kind. As well as anti-nationalists who consistently oppose all nationalisms, there are also those who support some types but oppose others - for example, many civic nationalists have a principled opposition to non-civic nationalisms. A consistent civic nationalist who took such a position would have to be an anti-Zionist, but would have no in-principle objection to Israeli civic nationalism.
It is undeniable that many people who identify as “anti-Zionist” do end up espousing antisemitic views, and sometimes even use “anti-Zionist” as a more socially acceptable synonym for antisemite - at the same time, there are several ways someone can be anti-Zionist without necessarily being antisemitic, and many people who are. The equation “all anti-Zionism is antisemitism” which the US Congress is promoting here is a very ignorant oversimplification
