Jews see themselves as part of a dual family, both the children of God and Jacob (Israel). In a community that's so much like a family, there really is no need to seek out converts. In fact, they don't really want converts. No crusades or missionaries...just people faithful within their family. However, should someone choose to convert, it is forbidden by Jewish law to bring it up as a weakness on that person's part.
While the myths of the Jewish people will claim them the chosen people of God, they have never imagined that they were the only people in the world. They are not the only religion allowed to exist. They are fully aware that other people have other faiths, and that's just fine.
In Judaism, the spirit of the law and the letter of the law are, in fact, the same thing. There's no double-talk, little misinterpretation.
There are other reasons Judaism is one of the nicer organized religions in my eyes, but those are the couple that stuck out at me in class the other day. It's just a nice, simple, unassuming and unaggressive religion. Perhaps it is those very qualities that have caused the Jewish people to be persecuted to heavily throughout the ages; more aggressive religious memes would seek to eliminate the more passive ones.
I don't think I'll ever be able to really follow any organized religion, but looking at them is at least a nice way to see what it is people believe they have to offer.
That being said, I still dislike Religion 101.
