Biden's remarks are what you're arguing for. Self-Identification of something you don't pass as, is not a legitimate identification. A tranny isn't a woman in the same way an atheist 'jew' isn't jewish. You have to rely on objective markers, and the objective marker for a religion is the religious practices.

Judaism is a religion. Every aspect of their ethnicity, is based upon the religion, even sex selection. Failure to abide by the religion is a forfeiture of the ethnicity because the entirety of the ethnicity falls within the religion.

The Zionist assertion, and it is a Progressive Nationalist assertion, that there is a jewish race which requires "self-governance" of said race, is complete bullshit. There is no international jewish racial diaspora. There can only be, at most, a Jewish "Ummah", and even then, it still requires religion to be a pinnacle part. And within that framework, there is no jewish Ummah. It is one of the reasons the jewish right have repeatedly sought to restrict the "Right of Return" against American and European jews, particularly if they are irreligious or have not had their family convert. The religion of the jews is the foundational organizing principle of all aspect of jewish society. When you separate out the jewish religion from the jew, he is no longer a jew because he is not organizing along jewish lines.

He could be semetic... but this is why anti-semitism being used as another way of saying "jew hatred" is false. Syrians are semites. Muslim Syrians are semites, yet we don't use this term for anti-Syrian bigotry. It is because the Zionists insisted upon linking judaism into a race, which it never belonged in.

These fake (read: Leftist) jews are trying to use judiaism and jewishness as a shield for an ideological cause; namely Zionism.

Not only are they saying: "As a white person..." while not considering themselves to be white, they are saying "as a jew..." when they are explicitly not jews, and should not be treated as one.

That doesn't make sense. One can not be within Jewish law, while explicitly rejecting jewish law for being judaism.

In fact, to looks like Leftists are trying to re-define jewishness in order to make sure their apostasy isn't used against them, in exactly the "right of return" I've previously mentioned:

QUESTION: If more than half the people who went on aliyah last year under Israel’s Law of Return are not halachically Jewish, doesn’t this render the traditional definition of Jewish status obsolete and it isn’t time for a radical rethink?

Rabbi Brawer: One might approach the matter of Israel’s Law of Return by recognising that standards of halachah and standards of citizenship need not necessarily be aligned. One may recognise that there are individuals who, according to the strict interpretation of halachah, are not considered Jewish, but who very much identify as such, and have much to contribute to the Jewish people and the state of Israel.

While it is only right that halachists be guided within the framework of halachah, one must at least recognise that there are other non-halachic frameworks that set out to define Jewishness.

This looks like Leftist subversion of Judaism to me.
