This is how Judaism is, we don't do things in the name of God but to become better people, Ethics and the Law are more important parts of the belief than worshipping or spirituality. The idea is that we grow as people to be responsible adults not to be constantly children looking to be led all the time. Christianity may have come from a small part of Judaism but there is very little in common, we have different thoughts, different practices, different writings and very different ways of expressing our beliefs. Judaism isn't Christianity without Jesus, the divergence is far bigger than that. I don't think the lack of tolerance is on my side by the way, I don't believe my faith is the right one for everybody, we believe in free will and everyone being responsible for themselves. Whatever relationship they want to have with any or no deity is entirely their business and their choices should be respected as being every bit as valid as everyone elses.
