You maybe think that you have a 'right' to feel confused as to why the majority of theists do infact and in very very real terms do get offended by every means the word can hold when they hear an atheist making parellels and comparisons of God to faeries and other fictional characters.That's because we take it personally and also we take it as either a fixed position of general dismissal or just plain disrespect.
Just faeries and FSM and UPI or all fictional characters? Isn't it offensive because the FSM and IPU were seemingly created to purposefully mock believers? Faeries are different in that regard, as are ghosts, space aliens, etc. If it is offensive simply because an analogy is being made between God and a fictional character, then there is really not much that can be done. Because one of the main points of making that anaogy in the first place is to show that we see your God
as a fictional character. If our seeing your God that way is offensive, then there is really no way to dampen that.
One of the reasons which may lead us to think that atheists do actually in some way or another have a faith deep down inside is tht we can't find any possible reason as to why they claim that they are only interested in religion just to broaden their perspective of the world of theists. I have a question to ask you and really and this time answer me honestly. Ever since you found out that Santa Claus was a popular cultural lie that parents tell their children about before Christmas, and after you've fully understood how he can't possibly exist even if you wanted him to?. Did you spend one more second pondering and trying to discover why other kids still believe him to be true? I highly doubt that. Because simply you grew out of it. It was just a phase and you were more than convinced that one day other children will find out santa clas is not real.
Personally, I never believed Santa was real. I grew up thinking Santa was a fun character like the Easter Bunny or Leprechauns at the end of Rainbows with pots of Gold. It never dawned on me that other children may actually believe Santa really exists until I was much older. I felt the same way about God. I grew up in a Christian society and I remember going to church as a child and hearing stories about Adam and Eve, Noah's Ark, Job and the whale, etc. They sounded no more real to me than other children's stories like Hanzel and Gretle, Jack and the Beanstock, or the Cat in the Hat.
I saw God and Jesus as something to take a bit more seriously, but I always say it as a cultural thing, something people pretend is real, not something they actually believe. I thought people went to church for comfort and community, and gave prayers for peace of mind in some sort of therepeutic sense, knowing the whole while that there is no actual God hearing them. I thought it was like writing something down on paper, like keeping a diary, etc. I was the opposite of theists who don't believe atheists exist. I was an atheist who didn't believe theists actually existed.
Only much later did I realize that people ACTUALLY do believe this stuff. And that some actually believe it LITERALLY. I did a double take when I realized that. I found it shocking and hard to believe, and absolutely fascinating.
Now, why do I find it more fascinating than young children who may actually believe in Santa? For a number of reasons. First, we are talking about fully developed, intelligent adults believing in God rather than young children still developing their minds and prone to fantasy. Second, religion permeates society at a much higher level. Missionaries don't go around pushing Santa. People don't go to war or kill each other over Santa belief. People don't form deep personal moral positions on things like abortion, contraception, homosexuality, etc based on Santa either. People don't base their entire lives, personal identities, circles of friends, etc around believing in Santa.
Also, Santa doesn't care if you believe in him, only that you are good. And Santa will not send you to hell and torture you forever if you do something he doesn't like. He'll just give you a lump of coal. So it isn't nearly as concerning as some people's visions of God are.
Especially that before a period of time it was fairly common that an atheist whom denounced his/her faith would refer to have been a former follower of any particular faith when they were younger but then suddenly lost their faith and now they switched arguements in which firmly saying 'No, despite the fact that some of us were brought up in religous house holds, we can't remember a time at which we ever actaully had any faith to begin with. We always lacked that faith in God other believers around us seemed to have'.
I personally was never a believer (though I still pretend to make my mom happy), but if you would like me to I can refer you to many atheists who were. I even know some who are former ministers of fundamentalist christian churches. I don't know many ex-muslims who are atheists personally but I do know of them.
Which also brings up the arguement that 'there are no atheists in foxholes' is what based the foundation that an atheist was a believer but lost his her faith because of their distrust in God or failure to observe patience. I know you didn't ask for such a lengthy reply but I thought if would give a broader perspective of why we actually aren't projecting but rather predicting.
"there are no atheists in foxholes" is the argument that atheists who fear for their lives will turn to God. This is of course not always true, but it does happen sometimes. I don't think it should surprise anyone that it happens. Desperate people will take desperate measures, including irrational measures, grasping at straws. It isn't just Gods that desperate people will turn to. They will also turn to psychics, mediums, spirit healing, and all sorts of other things they would otherwise have seen as irrational.
As for becoming an atheist because of distrusting God, that makes no sense to me. If you hate God or don't trust God or turn against God, you by necessity believe in God. I could picture somebody wanting to believe in God and losing patience waiting for some evidence that he exists and calling that "losing patience with God" I suppose.
