I agree with MW1 for the most part. Things like Religion, patriotism, goverment, race, etc have been used throughout history by people to manipulate others. Because like anything that involves humans, it can and will be corrupted by evil and manipulative people for thier own purposes. The sooner people discover this and develop a lack of trust in other people to remain virtuous, the better. It's simply not out nature to be selfless. It requires real effort. People in higher places of power and wealth did not get to higher places of wealth and power by being selfless so they should be the least trusted in my book when trying to move the masses for a cause.
However, that is not to say there isn't a god. We will find that out for ourselves eventually and can choose for ourselves if we want to believe there is or is not one until then. Well ... I guess if we don't find it out when we die, then there isn't one I guess. LOL.
