Judaism is the "religion, philosophy, and way of life" of the Jewish people.
Judaism is not a race because Jews do not share one common ancestry. For instance, Ashkenazi Jews and Sephardic Jews are both "Jewish." However, whereas Ashkenazi Jews often hail from Europe, Sephardic Jews often hail from the Middle East. People of many different races have become Jewish over the centuries.
Judaism is not a nationality
Although today Israel is often called the Jewish homeland, being Jewish is not a nationality because Jews have been dispersed throughout the world for almost two thousand years. Hence, Jews come from countries all over the world.
Judaism is both a cultural and religious identity
Being Jewish means that you are part of the Jewish people, whether because you were born into a Jewish home and culturally identify as Jewish or because you practice the Jewish religion (or both).
Cultural Judaism includes things such as Jewish foods, customs and rituals. For instance, many people are born into Jewish homes and are raised eating blintzes and lighting shabbat candles, but never step foot inside a synagogue. A Jewish identity is automatically bestowed on babies of Jewish mothers (according to Orthodox and Conservative Judaism) and of Jewish mothers or fathers (according to Reform Judaism). This Jewish identity stays with them throughout life even if they don't actively practice Judaism.
Religious Judaism includes the beliefs of the Jewish religion. The way a person practices the Jewish religion can take many forms and partially for this reason there are different movements of Judaism. The main denominations are Reform, Conservative, Orthodox and Reconstructionist Judaism. Many people who are born into Jewish homes affiliate with one of these branches, but there are also those who do not.
If a person is not born Jewish, s/he can convert to Judaism by studying with a rabbi and undergoing the process of conversion. Merely believing in the precepts of Judaism is not enough to make someone a Jew. They must complete the conversion process in order to be considered Jewish. Though the different branches of Judaism have varying requirements for conversion, it is safe to say that the conversion process is very meaningful for whomever decides to undertake it.

Israel's Racial Purity Laws
This is a study file of articles published mostly by Jews about Jewish separatism whereby Jews seek to keep their own race pure. The irony is that their leaders seek all other races to intermix and such Jewish groups as the ADL and ACLU have expressed some of this irony from time to time.
"Jewish Majority Vital for Israel's Future"

JERUSALEM - Safeguarding Israels Jewish majority must be a national priority, according to Israeli Prime Minister Ehud Olmert. We must ensure that the State of Israel has a definite Jewish majority, or otherwise the notion of a Jewish state will become void, the Israeli prime minister said on Monday during a Knesset address in memory of Zionist visionary Theodor Herzl. Olmert, like his predecessor Ariel Sharon, has justified his plan to quit parts of the West Bank by invoking the demographic threat posed by growing number of Arabs.
"Changing Israel's Marriage Law"

Non-Orthodox Jewish couples are forced to submit to an Orthodox marriage ceremony with an Orthodox rabbi and are compelled to attend classes on family purity. No Israeli may marry outside her faith community. Hundreds of thousands of Israeli citizens from the former Soviet Union who are not Jewish or whose Jewish ancestry is in doubt are unable to marry at all inside Israel. And more women every year are chained to men they wish to divorce but who will not give them the get required by Jewish law.
Despite these problems, Israels Religious Zionist and haredi communities insist that holding on to the marriage reins is necessary for Jewish continuity. If Jews are allowed to marry outside Orthodox parameters, they say, a split in the nation will result.
There are two related worries: intermarriage and illegitimacy. Children of marriages forbidden by Jewish law, or halacha (for example, unions between a kohen and a divorcee, between close relatives, or between a man and a previously married woman who did not undergo a halachic divorce) are considered mamzerim. They and their offspring, stigmatized with an irrevocable brand of illegitimacy, may marry only other mamzerim. A split in the nation, the argument goes, will follow: mamzerut will increase dramatically and it will be difficult to keep track of mamzerim to ensure they do not wed non-mamzer Jews.
On Problems of Jewish Intermarriage & Loss of Jewish Identity

Let's be honest. We are losing the battle of Jewish identity. Intermarriage is growing. There is a lot of ignorance. Two generations of Jews in America have passed without their being taught to be Jews. .... A stronger Israel working with American Jews on this challenge cannot only make each stronger, but will reinforce the deep ties that bind us one to the other.
Israel's Marriage Law
Znet Magazine

Israel's Parliament has passed a law preventing Palestinians who marry Israelis from living in Israel. The move was denounced by human rights organisations as racist, undemocratic and discriminatory.
Under the new law, rushed through yesterday, Palestinians alone will be excluded from obtaining citizenship or residency. Anyone else who marries an Israeli will be entitled to Israeli citizenship. Now Israeli Arabs who marry Palestinians from the West Bank or Gaza Strip will either have to move to the occupied territories, or live apart from their husband or wife. Their children will be affected too: from the age of 12 they will be denied citizenship or residency and forced to move out of Israel.
Amnesty International and Human Rights Watch sent a joint letter to the Knesset, Israel's parliament, urging members to reject the bill. "The draft law barring family reunification for Palestinian spouses of Israeli citizens is profoundly discriminatory," Amnesty said in a statement. "A law permitting such blatant racial discrimination, on grounds of ethnicity or nationality, would clearly violate international human rights law and treaties which Israel has ratified and pledged to uphold." B'Tselem, an Israeli human rights organisation, joined in the criticism of the law. Yael Stein, a spokesman, said: "This is a racist law that decides who can live here according to racist criteria."
Some Israelis believe they are sitting on a demographic time bomb, with an Israeli Arab community, already 20 per cent of the population, growing faster than the Jewish population. The discrimination is not only against Palestinians, according to human rights groups, but against Israel's own 1.2 million citizens of Palestinian origin as well. The overwhelming majority of Israelis who marry Palestinians are the so-called Israeli Arabs - Palestinians who live in Israel and have Israeli citizenship.
"This bill blatantly discriminates against Israelis of Palestinian origin and their Palestinian spouses," said Hanny Megally of Human Rights Watch. "It's scandalous that the Government has presented this bill, and it's shocking that the Knesset is rushing it through."
The government pushed the vote through at speed, even agreeing to consider it a vote of confidence to get it through. It was passed by 53 votes to 25, with one abstention. Gideon Ezra, a cabinet minister, said: "This law comes to address a security issue. Since September 2000 we have seen a significant connection, in terror attacks, between Arabs from the West Bank and Gaza and Israeli Arabs." Since 1993, more than 100,000 Palestinians have become Israeli citizens through marriage, Mr Ezra said. But B'Tselem pointed out that only 20 of those 100,000 have been involved in suicide bombings or other militant attacks.

"The State of Israel practices racism and discrimination in its laws towards the Arab population since before imposing the racist marriage law which was passed by the Parliament on the 13 July 2003. The Israeli Parliament voted to block Palestinians who marry Israelis from becoming Israeli citizens or residents, erecting a new legal barrier as Israel finished the first section of a new physical barrier against Palestinians West Bank."
