Just imagine how bad the world would be without Judaism, Christianity and Islam?

Yes how bad would it be? It would be so bad that people would stop killing each other over different beliefs. It would be so bad that human beings could live by their natural and practical human values rather than values contrived from supposed all knowing beings, values that one cannot attain. Values that even those who propagate those philosophies cannot adhere to. It would be so bad that people wouldn't have to live their lives with guilt that is not theirs and certainly not properly igned. It would be so bad that people could live their lives without the interference of others. The interference of those who think they have an ultimate and undeniable mandate. That mandate being to force others to adhere to their philosophies, usually at the point of the sword. It would be so bad that some people would have to mind their own business. It would be so bad that scam artists couldn't solicit funds from those they preach invalid doctrines to and receive special favor to avoid taxation. You got to be kidding. Judaism, Christianity and Islam are not ets, they are cancers that are strangling and killing human progress and freedoms.
