I have long argued that for many, Orthodoxy is essentially Judaism without G-d. It is just a convenient social context for members of the tribe. Here is an article where a practitioner admits it.
What bothers me more than the fact that he and so many others are living a lie [i.e. they practice but they don't believe in what they are doing] but that it doesn't even seem to bother them. If someone has doubts we have a vast corpus of literature dealing with matters of faith that guide, enlighten and remove the fog created by our physically dominated existence. But all too often people aren't willing to expend the effort to learn. People spend far more time researching a vacation spot they are considering than the purpose of their existence.
They are missing out on so much.
SAD.
