Who here is Jewish?

It doesn't make you a Jew, it makes you a descendent of Jews and with that comes both the biblical burden/priviledge (that you're welcome to ignore like, most modern Jews do). Judaic lineage is based on spiritual souls and not bloodlines. Look into how Jews percieve death.

Judaism is not the only religion that does this, by the way.

Courage - I'm not sure I'm following you with the difference between a Hebrew and a Jew. There are Chinese Jews who are every bit as Jewish as the Mesopotamian Hebrews. Their tribes trace all the way back without any conversions needed. Same with the Jews of India.
