Suppose you got two hours with the pope in a one on one. US Presidents don't get that, but this is imagine.
You are brilliantly devastating and absolutely convince him that his church is the biggest fraud ever perpetrated on earth, ever!
Now what? Does he resign? and walk away? Does he instruct the down command to dismantle everything, sell all the good stuff and turn the proceeds over to science, research, and distribution of food and medicine to the needy?
Or does he go out on his balcony and wave at the adoring crowds, have you thrown out and proceed as though nothing happened? He is a man after all. The world kisses his ass and anything else he wants kissed, you could hardly have a better job, especially if you are queer. Think about about the cool drag you get to wear, not to mention all the gilded rococo shit and statues of naked guys everywhere. Even Elton John has got to be a little envious of that gig.
Same thing goes for any church.
The god part is the hook. Heaven and hell keep you in line, sort of, but the pay off for the schmucks in the masses in the sense of belonging. Somewhere to go something to do. Bingo on Wednesday night, Picnics in the summer, get together's on Sunday, really cool buildings to hang out in ( sometimes) . A chance to sing and dance in front of an audience, blah blah blah.
Atheists want everyone to admit there is no god. ( I think a lot of the faithful already think this, but just like homos used to and still do, they go along to get along, and the perks seem worth while).
What have atheist got to offer? A meeting hall? A summer camp for the kids? A cool bus to go an a pilgrimage someplace? Virgins? Everlasting bliss?
Kind of a no brainer, they stick with what they know, because everyone they know does the same.
You can substitute football or hockey for a while for some of them, but the season always ends, and then their lives are empty again, and they have nothing to talk about. Quoting the rule books to each other just isn't the same kind of fun.
So if you do imagine no religion, what do you imagine will take its place?
Where do people go for comfort consolation and community? What organization will be readily at hand to bring you cake and blankets when your house burns down, or cry for your dead kid, or promise you that no matter how bad your life sucks, it will be better when you are dead and go to heaven, ( IF YOU BEHAVE)
Mormons may be dicks, but they come through when you need help. Catholics rape and kill, but they build hospitals and schools. Jews are very big on education science and the arts. What do atheist have to offer to compete with that?
