After going through the first two pages I kind of got sick of the bickering >.>;;
For referance though, most people who "follow a religion" have no clue whot it is they actually follow. They don't understand their beliefs, they don't even try to grasp why whot they believe is the way it is. They just assume it's infalliable (delusional at best), or go along with whotever they're told (inferiority complex?), while some use it as an excuse to 'prove' that they are 'better' than everything else as they are a 'child of god' (pseudo-god complexes whee!), or do so because they fear hell/afterlife/retribution for sins, etc, despite that these 'punishments' are intangible and can't be proven.
Are 'most' religious people little more than suffering from mental illness? Probably.
Does that mean ALL are? Not at all, religion in and of itself isn't BAD or anything, it's just that the structured organizations ARE. If yeu take a look at things from a very pragmatic and rational viewpoint, and try to learn religion as a science, rather than a myth, I don't think that can be considered mental illness anymore, merely an expression of attempting to identify, quantify and understand one's surroundings in more depth. Which's perfect normal, to be honest.
It's when yeu don't want to understand yeur surroundings and are happy with just making up silly things (thunder is angels bowling? wth? Could be worse... I knew one person who honestly believed that their poo was pushed out their butt by tiny itallian men with brooms for some reason... don't ask, I didn't) to explain away stuff without actually trying to figure it out on purpose. If yeu stop caring about trying to understand things, and just accept them as they are, that immediately tells me that yeu have stopped learning and have no intention of continuing to broaden yeur horizons. Sometimes yeu have to just accept things as they are, but it doesn't mean yeu shouldn't question them as well. It's possible to enjoy something just 'as it is', yet still want to learn more about it too. Some people just don't get that and figure questioning the nature of god or the universe is somehow 'wrong'. That, is something I shall never understand, especially when their own holy books, torah, qoran (I can't spell it), bible, etc, tell them to question things and they will one day become godlike in their own way.
