A wise man once said, "even if there is no God, Man has to create him".
Friedrich Nietzche, who was the son of a pastor, said that "God is dead", and landed in a lunatic asylum, trying to prove his point.
Since the advent of "institutionalized religions", wars were waged in the name of God. Religion (not God) has been, once too often, a curse to mankind. It has often been politicized (as correctly mentioned by you) for the sake of economic conquest, rather than spiritual.
I do believe in "GOD". However, while I accept the need for religious institutions as a necessary evil, I do not surrender my mind to them (meaning the "dogma").
As easy as that may seem to you and me, a vast majority of people (more so, those who aren't capable of “thinking” logically – whatever the reason may be) need these godmen to justify their actions using God as a tool of convenience. Therefore, one's perception of God, would depend a lot on Culture.
Culture is the totality of socially transmitted behavior patterns, arts, beliefs, institutions, and all other products of human work and thought. Culture is learned and shared within social groups and is transmitted by nongenetic means.
The "Godmen" (not "men of God") on the other hand, manipulate the ethics/ laws to influence the politics, thereby reaping the harvest from "lost souls". Therein sets in the corruption of "values" espoused by religions.
While it may be easy for one to say that "all Gods are One" or ""your God and my God are one and the same", it would be advisable for one to remember that people differ in their perception, definition and understanding of "God".
Therefore, while it may be correct as you understand, define and perceive God, it may not be the case with another. This difference in opinion needs to be respected first and foremost, should we discuss the nature of GOD.
These, I believe, are the facts that, both you and OU have been trying to illustrate in your own ways.
Although OU had mention the word "God", what he appears to me to be condemning, is actually, Religion.
