The ugly duckling (habarvazon ha’mechoar) thought all his life that he was a duck, until one day he looked into the lake and saw that he was actually a swan. So is he a swan or a duck?

The case of whether one is a Jew or not is -in my opinion- clear-cut. You either are technically a Jew or you are not. If you are not a technically a Jew then eating falafel and putting on tefilin daily will not make you Jewish. Religion is the only common aspect of Jewish people around the world. Whether one follows all, some or none of its laws is another matter.

You say: “A Jew is whoever possess Jewish culture”. And what is ‘Jewish culture’ one may ask? How much of that Jewish culture one has to possess in order to be considered a Jew? What about gentiles who are a scholars in Jewish history, Bible and tradition are they Jewish?

The questioning of ‘who is a Jew’ comes mainly from secular quarters. Many find the whole religious experience meaningless and seek to redefine Judaism on secular terms. That’s fine. People are free to call themselves whatever they like, but that does not transform then to that which they call themselves. As it happens being a Jew has its roots in a religious tradition. For better or worse we are stuck with it. Anything else is ‘like Judaism’; ‘good enough Judaism’; ‘sort of Judaism’; - for some - but not Judaism.

This questioning of 'who is a Jew' came from religious quarters, as well. In any case, just because a culture is deeply religious in nature, doesn't mean that one has to be religious in order to stay a part of it, to develop it.

I agree. Indeed the majority of the Jews, in Israel and elsewhere are not religious. I was merely questioning the assertion made earlier in the discussion that having absorbed some Jewish culture qualifies one as a Jew.

Einstein said it many years ago: “It’s all relative”. There are two possible points of view to the debate whether you are Jewish or not.
1. As the world sees you.
2. As you see yourself.
There is no doubt that the world considers you to be Jewish. After all, if your mother was Jewish, then technically you are Jewish too, and there is nothing that you can do about it. In addition, you live in Israel (the Jewish state), and you were educated in Jewish schools. I suggest that you will have great trouble convincing anyone that you are not Jewish (in their eyes).

As to how you see yourself? Well, that’s up to you. Evidently you are a free thinker and entitled to your opinion. After all, no one knows you better than you do.
So that’s it, everyone is right relative to their point of view.

The link works quite well for me.

Well, are you also not going to live according to Nature's directives? Will you walk off a cliff, to show your independence of Gravity?
Face it, many decisions one makes in life are in response to pre-existing conditions - if you're going to play the "I want to be independent game," then fine. But leave your hypocracy to yourself.
