If you research the history of some of the more prominent Atheist, now and in history, you'll see there was a traumatic event in their early childhood. This of course caused them to turn their back on God. Note... turn their back, They didn't suddenly decide their was no God. Otherwise what would they care? They are all about selfishness. If they are a true Atheist they wouldn't campaign against God. They simply wouldn't care. So, then who or what are they really angry at? Its not a campaign to disprove God, its a campaign to turn others away from God.
They know He exists. They wont admit it. And, they have yet to disprove He exists.
