Currently, there are very few pressures placed on the Jews. Most state-sponsored and church-sponsored persecution has ended.
So now what we’re seeing is an assimilation because we no longer need to assert ourselves as Jews. We don’t have to live in “Stetls”(projects for Jews), we’re no relegated to certain cities, there are no more pogroms today. So we’ve spread out. A majority of our formerly community acquired Jewishness and closely held laws and such have boiled down because of this.
There are several groups of Jews, however who have held fast to the word of God. In America, it’s the Hasidims and the Orthodoxy. Hasidims can be very separated from society sometimes, and can live in communes or other smaller societies. Orthodox are still rather, well, Orthodox, and follow many, if not most Jewish law including Kosher dietary laws and not driving on Sabbath or using electonics, Etc.
These two groups have mostly respect for each other, but the Hasidims are typically still a bit wary of anyone less Jewish than them.
Then there’s the Reformed/Assimilated/California Jew(Like me :)). A lot(but not all, or most), are typically like me. I unfortunately have no religion now. I will probably marry a “shiksa”. If I find religion, I will tend to go back to my roots, and I will try to raise my child in a family that will teach them both sides of their parents religions’(If I do marry a Christian, or other gentile religioned woman).
We’re not fully accepted by the conservative/Orthodoxy, and not at all by the Hasidics.
Even though I’m Reformed, I’m an Ashkanazi/Eastern Euro. Jew. I wouldn’t say I was “Jewish-looking”, but I have very olive skin, and dark hair(with lots of Russian red), even though my family, up to my mom’s generation was totally Jewish. My friend, who is an emigrated Georgian Jew, OTOH, looks VERY Jewish.
So, we’re a very dynamic culture as a people, with very homogeneous backgrounds. We’ve interbred for thousands of years, mostly for survival, and have now disbursed. We’re not exactly a race, but we’re certainly more than a religion.
