Hmmm, could it be true? Lets see.
Where did niceguyism originate? The Council of Niceguyea?
Where did gentleology originate?
Where did goodfriendlishness originate?
You don't know me. I am an atheist, which means I don't believe that there is a god or gods. I decided this when I was 11 years old and at the time I knew nothing of the crap you mentioned. Half a century later I am aware of many ideas from many sources, some of which I adhere to, others of which I reject. None of which have fed my atheism they way you imagine. My mind is not so simple that I think that any one ism can save or ruin the world. It is not so simple that I think the use of big words and heady concepts will excuse any of many voluntarily inhuman beliefs.
I don't need help not believing in a god. I don't need cultural or social or other assistance. I can do it on my own. It is a yes or no proposition, and I can decide the answer without resorting to the tomes and philosophies and knowledge bases you allude to. I, for one, have never tried to put the pseudo in pseudo-intellectual.
I'm not stupid enough to be that dumb.
