That was a very difficult question you asked, TP. You knew I'd show up in this thread, didn't you? I have to apologize in advance for not being aware of any other discussions that are taking place on HoF, as I've been away for a while.

So maybe it isn't the case that your current agnostic beliefs are as incompatible with Judaism as you suppose?
Agnostic belief IS incompatible with Judaism, which is, after all, a religion. As TP pointed out, if an agnostic converts to Judaism - what is it, exactly, that she is converting to?
That said, I was at a woman's study group at my synagogue, and the topic was "How women talk to God." There was maybe a dozen women there, and at least 5 of them began by saying that they are not sure there was any-One to talk to. Yet they were all at this Torah study group.
There's also a group of "Humanistic Jews" in the area, who view Judaism as a cultural tradition and a guide to moral behavior.

I see Christianity as essentially offering everyone the opportunity to become Jewish, that is, to come into the family of God's chosen people.
I think this is historically true.
Point of interest: At the same study group, our rabbi told us that the reason for the rule of matrilineal descent was the large number of Roman matrons who converted to Judaism. Among other things, Jewish women 2,000 years ago had a lot more rights than their Roman sisters (or American women of a hundred years ago). Their husbands were well enough where they were, and even those interested were deterred by the requirement of circumcision (which Christianity later allowed them to circumvent). So the question rose - were the children of those women converts Jewish even if their fathers were not? As the rabbi put it, the decision was made in favor of having more Jews.
Now in the Reform community, there is a growing opinion that children with any one Jewish parent should be considered Jewish if their families are willing to give them a Jewish education. Again, the logic is in favor of having more Jews.

And every year, in celebration of Shavuot, one ought to feel that one is at Sinai, with Moses, accepting Torah. It is an ongoing act of volition.
TP, that's the best answer I can give you. As you know, I'm sure, there is a belief that the soul of every Jew ever to be born was present at the moment of the receiving of Torah. I don't know how much of my genes are "Jewish", and I don't think that it matters in any practical sense. But in the spiritual sense, it matters a great deal.
Does that apply to a convert? I think it does. As the group of desert wanderers accepted the Torah, so does a modern convert choose to shoulder his or her part of the burden and the privilege.

It is not really a religion because you will never be considered something else by your enemies when the chips are down, no matter what church you join. One definition of Judaism offered during early debates over the Law of Return was: a person is a Jew if they would have died in the Holocaust
This is also deadly, in my opinion, because it gives backhanded validation to what has been called 'Jewish self-hatred.' There is some portion of the Jewish community that really just does not feel Jewish and does not want to be Jewish but considers itself without alternative, unlike every other American ethnic group which can, within a generation or two, expunge their ethnicity if they want to.
Jn, I really don't see how your second paragraph follows from the first. The reasoning behind The Law of Return, at least in part, was to provide a shelter to anyone who would have been endangered due to their Jewish identity, as perceived by themselves or those around them.
I also don't see how any other ethnicity can "expunge" itself. Can a black American declare him/herself to be "white" and be free from prejudice? Can a third-generation Japanese do that? I've heard of Asian Americans - born in America to American-born parents - who are constantly being asked where they are from, or complimented on their excellent command of English. There is no way for them to head that off, no matter how much they want to "expunge" those questions.
And that reminds me…
Once an elderly Jew on the Subway saw an elderly Black man reading a newspaper in Yiddish. After some hesitation, the Jew addressed his neighbor, "I beg your pardon a thousand times, but isn't being Black hard enough?"
When I was growing up, my Jewish looks were as conspicuous as skin color. Nobody ever asked what my religious beliefs were - I was defined by my appearance. And I think that is one of the reasons why many Jews are reluctant to encourage converts, with the exception of those who marry Jews. Personally, I do think there may be a disconnect between a convert's uninhibited joy at discovering the rich traditions of Judaism, and their new community, which experienced and inherited the risks and pressures that go along with being Jewish.

Can someone become not-Jewish? Can someone renounce being Jewish?
Sure someone can renounce being anything they don't want to be. How would that work, though? Can someone become non-Irish? Non-French? Non-Arab?
Faramond wrote:
Who insists that Jewish converts to Christianity have to leave behind their Jewishness? Is is only Christians who do this? Do most Jews think it's possible to be Jewish and Christian as well?
Would it help to answer your question if I said that the concept of original sin does not exist in Judaism?
Yes, I'm answering a question with a question. I'm Jewish.

But if someone views his or her own Jewishness as acceptance of the Torah, then there must also be freedom to walk away from that.
I am not the best source here, but personally "acceptance of the Torah" does not ring right to me. It's more "inheritance" than acceptance. It's being part to something handed down over millennia. Like the prodigal son of the parable, one can turn away, run away from that inheritance, but it's there, waiting to be picked up.
