I see that I did not answer the immediate question.
No, Zionism/Judaism is not racist, at least not in the common sense of the word.
Yes, it is true that Judaism is partly a people – as are the Irish, the French, the Italians, the Americans, and the Japanese – with their own traditions and customs. It is possible to become Jewish by conversion, as it is possible to become Irish, French, Italian, American, or Japanese by changing citizenship. If Judaism is racist, then so are all nationalities.
When the Ethiopian Jews were being persecuted, Israel rescued them. No other nation bothered. There are Jews of all races, and all are welcomed as citizens of Israel by nature of being Jewish. This is one of the broadest open-door policies of any country.
So the answer is, no, Judaism/Zionism is not racist. At least, no more than any other nationalism. Like every other nation, Israel is not perfect, but there is no point in singling her out.
There is one other notion that is sometimes mis-interpreted (by anti-semites) as racist, the notion that the Jews are a “chosen people.” This gets distorted all out of context by the virulent racists. The simple meaning of “chosen people” is that Jews were chosen by God to be the recipient of the Ten Commandments at Mount Sinai, and to follow special religious precepts. That’s it. There’s no “superiority” in this concept – to the contrary, it’s a significant burden. And note that anyone, of any skin colour or national origin or gender, can take on that burden by conversion and so join the “chosen people.” If this is racist, then so is the Catholic Church, or any Protestant Church, or the Muslims, or the LDS, or any other religious group who feel that their religious practices were specially ordained by God.
Apparently mswas thinks that all nations and all religious groups are, in fact, all racist. I disagree, I think that blurs what really IS racist. However, even if I grant mswas’s point of view, there is no reason for the declaration to single out ONE such religion or nationality. If the declaration had condemned “racism, anti-semitism, and all religions,” or “racism, anti-semitism, and nationalism,” that would be a different kettle of phish. But to single out Israel is ludicrous.
