Many people on this thread are of a younger, more educated and modern generation. Few of us, if any, "non-believers" are arguing the existence of god with the intention of taking the source of happiness away from others.
The ultimate goal of life is to reproduce/continue... religion, imo, had a big role in establishing the foundations of human morality. Dogma was a core philosophy that led the way to establish a code of conduct and sense of purpose. That being said, it does not belong in this modern world anymore. It is time for mankind to graduate from kindergarten and move on to 1st grade, leaving outdated ways of thinking behind.
Dogma is only a tool for the greedy, and a clutch for the uneducated to feel a sense of justification in rejecting intellectualism. Reproduction is our purpose as a living thing, but the quest for knowledge is our purpose as a human. The goal isn't to disprove of God, but to find the truth.
War, murder, rape, molestation, corruption, and power... a species has enough of this backwards thinking to handle on it's own natural tendency to produce errors and anomalies in the system... it does not need religion to act as a multiplier to these evils and work as control panel over the ignorant. Knowledge is key to reducing the evils in this world; not religion.
