I once received a message from a man who told me that many Jews do not like gentiles.
He knew this because his (Jewish) girlfriend's friends and parents disapproved of him.
And the rate of intermarriage has grown dramatically in recent years: according to the Jewish Databank, the rate of intermarriage has risen from 13% in 1970 to 47% since 1996, though the rate of intermarriage seems to have stopped increasing.
The 2000 National Jewish Population Survey found that only a third of interfaith couples raise their children Jewish, despite increasing efforts in the Reform and Conservative communities to welcome interfaith couples.
This may reflect the fact that Jews who intermarry are not deeply committed to their religion in the first place: if something is important to you, why would you marry someone who doesn't share it?
Certainly, the statistics show that intermarried Jews are overwhelmingly less likely to be involved in Jewish activities: 85% of Jewish couples have or attend a Pesach seder, while only 41% of intermarried Jews do; 66% of Jewish couples fast on Yom Kippur while only 26% of intermarried Jews do; 59% of Jewish couples belong to a synagogue while only 15% of intermarried Jews do.
These statistics and more are sufficiently alarming to be a matter of great concern to the Jewish community.
I explained that these people did not disapprove of him because he was Christian; they disapproved of him because he was a Christian dating a Jew, which is another issue altogether.
